New Product – Power Series 3″ Intake for Mazdaspeed 3

CorkSport introduces an all new Power Series 3″ Intake System for the 2007 – 2013 Mazdaspeed 3


With much demand for wanting more air and a throaty roar from your Mazdaspeed engine, Corksport is proud to bring you our Power Series true 3″ Intake System.

Mazdaspeed MAF

We have so many people ask for bigger intakes and MAFs that we set out to make a better one. Traditionally most MAFs are constructed from a welded pipe with various fittings for the MAF sensor to sit on or they are machined tubes with various fittings welded or bolted on.

What are the limitations to the current way of doing things? Most companies call a 76mm (3”) MAF, 3” because the outside diameter (OD) is 3” or 76mm. That really doesn’t tell you the amount of air the intake can flow. It tells you that you are using 3” connectors but the  inner diameter (ID) could be anything.

For reference the stock MAF is 68mm ID. Once you are in the low 300whp range your MAF sensor will read 5volts. This means that your MAF is “topped out” and does not have the ability to adjust fuel trims and timing properly. To get the head room of tuning you must upgrade to a larger MAF diameter.

The Power Series 3″ Intake System is fabricated with a high polished 3 inch turbo inlet pipe and a true 3″ inside diameter MAF housing. The velocity stack design smooths air flow for maximum performance.

In order to increase the ability for a large MAF to flow as much as possible and still not top out we decided we wanted to “bell” the MAF entrance. This effectively increases the air velocity, flowing more air. This is almost a 10% increase in velocity over the non “bell” version of the same MAF. This is something that is not done on a welded MAF. You can also make the MAF any size you want so making a true 76mm MAF is possible. This added head room allows your mods to go further and gives you the ability to tune for more power.

To help with proper idle and cruise resolution we also added a splitter to straighten the air in front of the MAF giving a better signal to the ECU.

If you plan on upgrading or have already upgraded your turbo this upgrade is a must to keep your MAF sensor functioning within its calibrated range.

“… Most aftermarket fuel pump upgrades consist of changing the internal parts of the factory pump with an enlarged piston and sleeve. By enlarging the piston, you increase the volume of the pump; thus creating more flow and the ability to maintain pressure at higher power levels.

When you first start taking the fuel pump apart, the first thing you are met with is the sight of a strange black deposit in the cap of the pump. Shown above are the deposits common to most caps. The bottom is a machined surface that should be clear of debris. In order for us to more clearly understand the situation we sent the cap out to undergo chemical analysis.”

“Does size matter? When looking at the stock piston on the factory fuel pump you can sure say that it does matter. If you increase the piston diameter you increase the flow of the pump. We have decided to compare the similar internals first and then compare the APR pump afterwards.”

“Now that we have a good understanding of the basics for these high pressure fuel pumps we can start to really dig deeper into the specifications. One of the items we were really curious about were the materials used in the construction of these pumps. We decided to have the hardness tested and ascertain the materials used. The factory pump internals do not use any coating, the hardness test showed us that the internals went through a hardening process as the core was significantly softer than the surface. Because of these hardness requirements, many other aftermarket internals use a coating of some sort to decrease friction between the piston and the sleeve. As for what the stock internals are made from, we answered that. Except for the hardening procedure, according to their chemical breakdown, they match a common die steel, so nothing too fancy.”

“ … We then built all the internals available in SolidWorks and tested the efficiency of them all for flow design and volume. This was merely the beginning of our design phase but helped us realize many great ideas (as well as a few not so great ones). We ended up with a design unlike any other on the market that, according to the data, would be more efficient than anything on the market.”

“After choosing a very strong alloy for our internals, we then machine their tolerances to an incredible 6 microns! To make sure the tolerances are paired for life, we serialize the parts to prevent any issues and to track the life of the pumps. We then surface treat the pumps to achieve the alloys maximum strength; only after the maximum hardness is achieved do we apply our surface treatments to bring the overall durability to an even higher level”

How to Keep Your Mazda Healthy

How to Keep Your Mazda Healthy…

CorkSport Mazda

As a car enthusiast, I always want to make sure that my car maintenance is up to date. In general Mazda’s are very reliable but, whether modified or stock, the life of your car depends on maintenance. Taking good care of your car today can help you avoid paying out more in the future on repairs. Here are the top tips I’ve collected over the years and have applied to keep my Mazda in tip-top shape. Hopefully they’re as helpful to you as they’ve been to me.

Gasoline – Find What Works for You

To find out what octane your engine needs, first check your owner’s manual. The recommended level is often 87octane. Some models have high compression engines which are designed to utilize the octane levels of 89, 91 or higher. Ordinarily, your vehicle will not benefit from using a higher octane than is recommended in the owner’s manual. If your engine knocks or pings at the recommended octane level though, you may need a higher octane gasoline.

Knocking may occur under certain conditions. A small percentage of vehicles may knock because of variations in engines of the same model due to manufacturing tolerances, or because of an unusual build-up of engine deposits. Other factors such as extremely hot weather, changes in altitude or hard driving conditions may also cause knocking.

Are you planning on running alternative fuel for your modified car? More often than not gas alternatives for modified vehicles require tuning. Every owner/tuner has its preference but keep the following in mind when choosing between E85 or race gas:

·         E85 will generate significantly more power than your typical recommended octane gas, given the same amount of fuel. The burn rate with E85 is faster than standard 87 to 95 octane, plus you get lower temperatures and more power. The downside is that you will get worse fuel economy, and your Fuel Pump will need more regular cleaning.

·         The best thing about any race fuel is its consistency. You can count on the performance of the fuel and then tune accordingly. It makes things like elevation changes, ambient temps, etc, easier to incorporate into different maps.

Oil – Change it Religiously

Change the oil in your Mazda every 3,000 – 5,000 miles depending on the type of (regular, synthetic) oil you use. If most of your miles come from highway driving (driving at a set speed for long intervals of time), you may be able to change the oil every 5,000 miles, but if you do most of you’re driving in a city or suburban area, check your oil every 2,500 miles just to be safe. If the oil appears completely black, this is a sign that you need to have your oil changed.

If you change the oil yourself, remember to change the oil filter as well. If you take the car to a mechanic to have the oil changed, he should change the filter when he changes the oil. I always recommend the OEM oil Filter and Full Synthetic oil of your preference.

Tire Maintenance – Keep ‘em Rotated

Rotate your tires every 10,000 miles to prevent uneven wear (this means the back tires should be moved to the front wheels and vice versa). Also keep a very close eye on your tire pressure. Mazdas use tires with a very soft tread, which means your car grips the road better, but its tires are more prone to leaks and breakage.

 Look in your manual to see what the tire pressure of your front and back tires should be, and check all four tires’ pressure once a month to make sure no leaks have appeared.

Air Filter – It May be Cleaner than You Think

Mechanics will often try to convince you to change your air filter every time you change your oil. However, you shouldn’t have to change your air filter more than once every 20,000 miles unless it’s excessively dirty.

Transmission Fluid – Keep an Eye Out

To protect your transmission and keep your car running for as long as possible, have the transmission fluid checked every 40,000 miles. In general, you don’t need to replace it until you hit 100,000 miles, but if you don’t check it and the fluid does burn out, it can ruin your transmission, a job that can cost more than $1,500 to repair on a Mazda.

Battery – Inspect it When the Time is Right

As long as you are careful not to leave the light or any other battery-operated extras such as the stereo turned on when your engine is not running, your Mazda’s battery should last approximately three to four years. When approaching the five- to six-year mark, be sure to have it inspected. It is better to be prepared than to have your battery die unexpectedly when you need to be somewhere.

What If?


As a longtime Mazda enthusiast, I’ve seen the company evolve in many innovative ways. Most recently, Mazda has focused their attention on improving the current Skyactive Technology lineup, including the SKY-G 2.0-liter gas and SKY-D 2.2-liter diesel engines.

This technology is great for those looking for good fuel economy and better engine output. But what about the enthusiast who, instead of seeking MPG, is drawn to a fun, high performance vehicle they can enjoy driving 24/7?


Here’s what I’m thinking.

Sure, the 2.3 MZR engine had its ups and downs and can be improved by the enthusiasts who own them. But, I imagine something beyond what we have now. Consider this. What if the next lineup of Mazdaspeed 3’s had a 2.5L MZR engine with an upgraded turbo and a High Performance Fuel Pump (HPFP) to help with the volume and pressure to produce an ideal 320 HP beast that will scare your competition away?

But let’s not stop there. Let’s address the torque steer under acceleration with an all-wheel-drive (AWD) system. An AWD Mazdaspeed3 was shelved years ago; the automaker said the high price point wouldn’t be saleable and the hatchback style wouldn’t be attractive to consumers. But now, hatchbacks are growing in popularity and perfectly positioned to rival any competitor. This creates a great opportunity for Mazda to introduce this next generation vehicle. With that in mind, I ask that today we raise our fists in solidarity for this type of Mazdaspeed innovation.

The Most Exciting Car Parts Order Ever?

Every CorkSport Part in Triplicate Please

I get as excited as anyone when I have car parts on the way. I check the tracking number 10 times a day, watch the front door like a hound dog, and sprint to the door faster than a K04 can spool when I hear a doorbell.

“Here! Finally here!” I triumphantly yell as the UPS, USPS, Fedex or other friendly mail courier hands me my package.

I don’t care if it’s a new turbo, a FMIC, or simply some new windshield wipers for safety, I can hardly contain my excitement. When that delivery man knocks on my door, if any friends are around, I practically bowl them over as they dive for cover.

“What is wrong with you man? It’s just car parts! You are WAY to excited.” They say.

I have become known as the “excited!” one, around my friends.

Then I found this.

No way. If you thought I was excited before, just wait till this bad boy pulls up to my driveway. What car parts do you have for me today delivery man? ……. maybe just…… AN ENTIRE CAR….. or every single CorkSport Part known to man, maybe it’s a new built engine, 4 sets of wheels and tires, a twin turbo setup, a front mount intercooler, coilovers, swaybars, and a small pet elephant.

That box is HUGE.

Honestly I have no idea what is inside, or even if it’s car parts, but I can tell you one thing. I want it, and if that box showed up outside my house, I might have a heart attack from excitement.
