Designed to replace the restrictive top-mount intercooler, the CorkSport front-mounted kit has been developed for optimal placement in the path of the inflow ambient air, allowing for maximized heat dissipation and reduced heat soak, a common problem associated with the stock top-mounted intercooler location.
The kit features a 21x10x3” bar and plate intercooler core, mandrel bent and TIG welded polished aluminum intercooler piping and custom-reinforced silicone connectors made from multi-layer nylon braid to provide strength and a smooth internal transition for less turbulent airflow. The kit includes stainless steel T-bolt clamps to ensure an airtight seal all of the needed installation hardware and detailed installation instructions.
During extensive testing, the CorkSport Mazdaspeed 6 Front Mount Intercooler showed an average pressure drop of 1.5-2 psi and a 10 to 1 temperature drop, meaning for every ten degrees of inlet temperature, the outlet temperature of the intercooler only goes up one degree.
The kit has been designed to integrate seamlessly with our popular CorkSport Stage II Power Series Short Ram Intake and can be purchased as a standalone kit to compliment your current short ram intake or can be purchased with the CorkSport Power Series Short Ram Intake for additional savings and power gains.
I have always had the itch to go racing on the track over the years but the price to do so always seemed like a number that was too high. I decided late last year that if I was going to hit the track I needed to get going on my dream. This is the beginning of the adventure I am taking to achieve this dream.
The best choice to get the license that I can find in our area was to race at Portland International Raceway with the SCCA. To get out on the track requires getting a SCCA novice permit. There are a wide range of things needed to get the permit. First thing you need is a race car. Since I had planned on going racing we have been preparing a car to do this but it was not ready to meet the challenge yet. After a few phone calls I came up with an intriguing option. The Oregon Region SCCA created a local class called IT-J. What do the initials stand for you ask? Well IT stands for “improved touring” and the J stands for “junk”. Yes I said junk. The local officials recognized the popularity of the Chump Car and Lemons car series so they made a class just for the junkers people race. The cars do need to pass an SCCA tech inspection like every other racecar out on the track but the budget building of the cars is taken into consideration so there are some things which are overlooked in the styling department.
My race car was loaned to me by several members of rotary power northwest, a local rotary enthusiast group. I was a guinea pig of sorts to test out the recently installed brakes and brake cooling system after an event showed the system to be a weak point in Chump Car racing.
With the racecar part of the puzzle out of the way, I had to get a physical with a specific set of SCCA forms to be filled out by my doctor, turn in my novice permit application, and get some safety gear.
The novice permit is straight forward as well as the doctor visit to get the forms filled out but the safety gear has a huge range of choices. It is required in the SCCA GCR (General competition rules) to have a fire resistant driver suit, gloves, shoes, baklava (sock for your head that fits under your helmet), helmet, and a HANS (head and neck support) device. Even shopping for the best prices the total bill on the safety gear came out to ~1700. The safety gear lasts for years if properly cared for so this is a large upfront cost you will only have to make once. A tip if you are purchasing a HANS device and helmet, make sure the helmet has the holes pre-drilled for the mounting point for the HANS. This saves you having to measure and drill your helmet. I purchased a bell helmet which had the points pre-drilled which made the installation of the mounting points a snap. The finished safety display of items is below.
Yes, I know, I look like they guy who died jumping a jag off the end of an aircraft carrier but there is a reason I went with the colors I did. Black is a color which works well with about any color and driving a race car is dirty which is hidden well on black.
Once you have all of your docs in order, your race car, and safety gear you get to wait for the event. I got lucky; the Oregon region SCCA school was a two-day affair with all of the required track time smashed into two days. This made it better than attending two schools to get the novice permit issued. In this case after passing the novice permit you get to race the same weekend at the 1st region SCCA event immediately after the school.
First things first, getting the car through the tech inspection. When you don’t own the racecar you are using this was a bit nerve-racking. I had an inspection done but it was found that the harnesses we expired at the end of 2011. There is nothing like a scramble to find a set of harnesses on a Thursday evening while you are in a drivers class which runs until 9pm. At 8:30pm a set of harnesses magically appeared in the driver seat of the car. By the time the class was over, I drove home and installed the new harnesses, it was midnight. With the words of one of the driving school instructors in my head saying “be there by 6:45am if you don’t have your tech sticker already” ringing in my head and “make sure you get plenty of sleep” I sacked out.
5 hours later a gently reminder to wake up blasted away to get me moving to the track to meet the time the teacher set out. I arrived early and got the car to the tent to await my tech inspection. The vehicle was remembered by the tech from the previous night so after a quick check of the harnesses the vehicle was passed for the school. Another quick check of my safety gear done and I was given an inspection sticker for my helmet and one for the car. I was ready to go.
After a quick drivers meeting where we all got a quick run down of the morning events everyone got suited up and we hit the track for some simple driving techniques and a trip around PIR to receive a preview of the track and what and where everything is. Next up was a drive and follow with several of the instructors to work out the driving line for everyone. Somewhere along the way I lost my instructor and another student to the pits for technical issues. I got to continue practicing turn in points and hitting the apex on the corners for another 20 minutes. Turns out the other student was busted for the 103db sound limit for the track. Moral of the story there is a vette with side pipes is REALLY loud, even louder than an Rx7 I was driving with a header and a pair of straight through mufflers.
After a drivers meeting and a quick lunch we headed out on to the track for another 120 minutes of track time to practice our lines, hitting markers, and learning the track. One of the items the instructors wanted us to learn is the turn markers and braking points. The reason for this is they had set up cones marking everything for us to learn and the cones were not going to be there the next day.
A sample of my instructions in my head for driving the track “turn four hit the late apex and head towards the small bleachers, quick on the brakes to set the outside tire and turn in to five. Aim for the orange climb through for the apex in five, a quick jab on the brakes to set the car for turn six which you need to stay in the middle of the track to start the turn and hit the next apex.”
After working on this for an entire day and some input on some tweaking of the car from one of the instructors I felt pretty good about driving around the track. The last driver session we got a surprise, the advanced drivers were put onto the track with us to give us the experience of much faster cars on the track at the same time. The advanced drivers were running a pair of Spec Miatas, a Porsche turbo, and a Viper challenge racecar. The Porsche and the Viper were insanely fast. You would see them in the rear view starting down the back straight. I was ¾ of the way down the straight and they would catch up to me by the end of it and pass me (and all of the other students) in the corners and disappear again for a lap or two. It is a very humbling experience to get blown past by those cars on the track.
At the end of the first day I had completed 260 minutes on the track and I was beat. Unfortunately I had an off the track incident while passing a 240z which required some minor repair work to the brake ducts on the front of the Rx7 and a quick inspection of the front brakes to see how everything was holding up. After 2 hours of work making sure the car was in good shape I got some much-needed rest.
The next morning the classes started up at 8:15 for a drivers meeting and hitting the track for four thirty minute driving sessions with a five-minute break between each one. In the Rx7 this meant I had to stop and get fuel after two sessions. It had rained all night so the track was really slick. After a brief meeting we headed to our cars and off onto the track. The 1st session was a get yourself up to speed and a last chance to memorize the track before the marker cones were pulled. On the first lap out I had an instructor spin out in front of me, several other students spin out, and another student blow completely off the track in turn nine and ten and end up against the tire wall. That black flagged the session so we all headed to pit row for them to clean up the mess. We were cut loose again on the track to finish out the session.
Session number 2 had more people going off the track along with our friend who went way off the tracking getting a chat from the instructors which I can guess was probably not a pleasant conversation.
The third session was a race just like what we would see in a normal SCCA weekend. All of the students were on the track with instructors and more advanced drivers at the back of the pack. I was stacked up with several other IT-J Rx7s towards the back of the pack in the starting grid. The green flag dropped and it looked like everyone was waiting for the car in front of them to go. I took off to the right with the Miata in front of me and passed eight cars by the time I hit the first corner. (I was next to the silver Rx7 in the picture below).
I was pretty proud of myself for the first racing start and getting past eight people. I managed to work myself past several others through the field until the faster drivers at the back of the field caught up later in the session.
For the last session of the day we had the advanced drivers out joining us again. By this point the track was really drying out and I was able to push it as fast as I felt comfortable in a borrowed car. I found myself checking glancing at the rear view mirror often with the threat of the Porsche and viper catching up to me and I wanted to make sure I was ready for them to go past.
We all headed off the track and went to the last drivers meeting. There were a few violations handed out (someone had pass on a yellow flag which is major no-no in racing) by the stewards for the day then we got what we had all come for, the novice permit signed off. Some of the students immediately signed up for the practice session to race in the region SCCA event the same weekend. My prize for the weekend is the novice permit and the office certificate granting stating we passed the school.
So what is next in my path to racing? Like I mentioned earlier CorkSport is building a racecar to compete with. I will divulge more on that project later but we need to have it together by April 28th and 29th for the double regional event. With two regional events under my belt I can apply to get my regional SCCA racing license and move up from the novice permit.

So you want to be a race car driver… August 4th, 2020CorkSport
CorkSport is pleased to announce the re-release of the highly anticipated CorkSport Mazdaspeed Protégé downpipe!
The CorkSport downpipe has been expertly designed to replace the restrictive piping of the Mazdaspeed Protégé stock downpipe. Mandrel bent 63mm piping is used to create smooth exhaust flow for dramatic increases in power. For lasting corrosion resistance and reduced heat transfer to the engine bay, the CorkSport downpipe uses polished T304 stainless steel and features TIG welds that offer superior arc and weld puddle control for a cleaner appearance and precise weld bead control.
The CorkSport Mazdaspeed Protégé Downpipe is just one of three parts that CorkSport has released in recent months to support the Protégé community.
Earlier this month we released the Mazdaspeed Protégé Intercooler Hose Kit designed to replace the stock rubber hose with strong, flexible, reinforced silicone that will allow for ideal flow in and out of the intercooler.
And late last year, CorkSport released the 2001-2003 Mazda/Mazdaspeed Protégé Skid Tray which will provide solid protection against rocks and road debris and is designed to prevent damage to key components of the undercarriage of the vehicle.
CorkSport is the proud new owner of Mazda’s newest addition to its line-up, the CX-5. Picked up straight from the port of Tacoma yesterday, the sporty new CX-5 will be helping CorkSport develop a new line of Mazda performance parts aimed at fulfilling the performance potential in the new SkyActiv engine technology line.
The CX-5 is available in three trims, Sport, Touring, and Grand Touring. We opted for the base sport trim which is currently the only option available with a manual six speed transmission. The Sport comes standard with seventeen-inch alloys, push-button start, tilt/telescopic steering, and cruise control.
The design is based on the Minagi concept car, and is Mazda’s first production vehicle to utilize the Kodo design language. The new five-point grille gives a real feeling of width, as it cuts into the headlights before leading to the lower center portion of the front grille and the interior is modern and clean and the driver-centric cockpit features a small, sporty steering wheel.
The CX-5 has the new SkyActiv 2.0-liter four-cylinder engine and includes a direct injection, variable valve and exhaust timing, a specially designed exhaust manifold and a high compression ratio of 13.0:1. The engine’s broad torque band, the new transmission, and the reduced weight work together to deliver good acceleration. The quick revving engine has an excellent mid-range punch and the engine delivers a smooth, bossy engine note.
The electric power assist steering system offers crisp, quick steering and highly precise control. The geometry of the suspension links and the bush characteristics are optimized to ensure light, linear steering response at mid-to-low speeds and excellent high-speed stability.
We have already began development of a new SkyActiv short ram intake which will be launching later this year along a with a number of other performance parts to support the new SkyActiv suspension and engine.
CorkSport is happy to add the CX-5 as our newest project car!

CorkSport Welcomes the CX-5 to the Family! March 9th, 2012CorkSport
Today, we are releasing our all-new CorkSport Stage One Power Series Short Ram Intake! Developed as an introductory package, the stage one intake replaces the factory airbox with an open intake system while maintaining the use of the factory turbo inlet pipe.
Unlike our classic CorkSport Power Series Short Ram Intake, this kit does not include an upgraded turbo inlet pipe allowing us to provide this introductory package for your Mazdaspeed. This affordable option for upgrading the Mazdaspeed 3 intake system includes our precision machined MAF housing made from billet aluminum with included air straightener, durable dry flow air filter, and custom-reinforced silicone connector.
This easy-to-install short ram intake forces volumes of air to your engine through the dry flow air filter and MAF housing and down the silicone connector providing a noticeable improvement in power along with improved fuel economy. Initially testing the CorkSport Stage One Mazdaspeed 3 Short Ram Intake netted peak gains of +12 HP and + 17 lb torque.
Choose from a red, blue or black air filter and MAF housing to customize the look of your engine bay, and polished T-bolt clamps to tailor the look of your intake system.
This was developed as an affordable alternative to CorkSport’s number one selling Mazdaspeed 3 Power Series Intake System with included turbo inlet pipe. By adding the CorkSport Mazdaspeed 3 Turbo Inlet Pipe, customers can expect to see an additional 14% improvement in airflow over the stock pipe and significantly decreased airflow turbulence by removing the restrictive nature of the stock pipe with the sweeping curves associated with the mandrel-bent aluminum 60mm piping used in the CorkSport pipe.
