CorkSport Officially Adds the MazdaSpeed Top Mount Intercooler to the Product Line-up

CorkSport is pleased to announce the latest addition to our product line-up, the premium-quality CorkSport Mazdaspeed Top Mount Intercooler (TMIC). The newly engineered TMIC is made from CorkSport’s own custom cast end tanks which are TIG welded to a 3” thick bar and plate core, providing added performance by removing the bottleneck restriction of the stock intercooler and increasing resistance to heat soak by using thicker materials. The cold pipe connection is CNC milled and drilled for a leak proof connection and all bolt holes have been capped off.

CorkSport’s innovative design allows for the reuse of the Mazda OEM plastic shroud leaving your engine bay looking completely stock; however an optional aluminum ring has been made available and can be customized to compliment the finish of any engine bay.

The CorkSport TMIC has been vigorously tested to ensure optimal characteristics. Testing completed on a SuperFlow test bench proved a 46% increase in airflow over the Mazda OEM intercooler. During the testing, the CorkSport TMIC showed an average decrease in pressure across the core by 53% and an increase in overall efficiency of 25% over the stock intercooler.

“After many months of design, testing, and data collection, we are proud to release our highly anticipated CorkSport Top Mount Intercooler”, said Rich Harris, President of CorkSport, “Our TMIC provides solid power gains and is a great value add to the Mazdaspeed 3, MazdaSpeed6 and CX-7 turbo. Pre-sales of the product have shown a strong demand in the marketplace for the newest addition to the CorkSport line”.

The CorkSport Top Mount Intercooler is available now for purchase at or by phone at (360) 260-CORK. The CorkSport Top Mount Intercooler features full color installation instructions and comes with all the required installation hardware.


The SFLA Mazda Crew hosted their second Epic Florida Meet at Lou Bachrodt Mazda on Feb 21st and CorkSport was invited to attend. Agreeing to attend and getting to the event which was 3230 miles away made for some tough choices for us. We decided to forego bringing a booth and parts show up with a backpack full of t-shirts, can koozies, and the new CorkSport license plate frames to hand out.

Lou Bachrodt Mazda is located in Coconut Creek which is about 45 minutes north of Miami Florida. The weather for the event was beautiful, 80 degrees with a light breeze all day. Compared to Vancouver, WA which was 45 degrees and cloudy, it was a huge difference for winter weather.


MazdaSpeed 6s

160 Mazdas showed up to the event and they ranged from a beautiful 1971 RX-2 to a 3 Rotor 1000+ Hp RX-8. The RX-8 was a beast with a turbo the size of my head.

There was a portable dyno on hand for the day but it suffered a failure which kept anyone from getting pulls completed. The failure occurred when the first car was on the first power run.

There was a great turnout of Mazdaspeed 3s, both 1st and 2nd gens. There were several standouts I saw at the show for both generations.

A visit from the Red Bull girls kept everyone going all day long. The aftermath at one of the garbage cans shows the carnage of drinks consumed.

Dead Redbulls. Deadbulls?

I would like to give a big thanks to the SFLA Mazda Crew for organizing the Epic Meet and Lou Bachrodt Mazda for hosting the event. For more pictures of the event check out our CorkSport Facebook Page.

CorkSport Top Mount Intercooler and Beyond

In following one of our ideals that our customers are the best source for new product ideas, we have been developing a Top Mount Intercooler (TMIC) for the 2.3L MZR engine. The original idea came from a thread on Mazdas247 started by azmavhockey3. The thread was started way back in August and was specifically put up to not only show us (CorkSport) that there was interest in this product, but also to get other users to input ideas and characteristics that they would like to see in a TMIC.

After getting feedback from numerous forum users we tested several designs of TMIC’s to see what would fit best with what the customer wants to see in a TMIC. The picture below shows one of our later iterations in the design and testing process.

Prototype TMIC

After testing airflow, temperature, pressure, and heat soak characteristics of the above design as well as the stock design, we modified our design slightly and came up with our final version of the CorkSport TMIC. We will have a full write up on the performance and design characteristics of the TMIC posted before we release the part in late March.

Production TMIC

Getting back to my reason for writing this: the origin of the idea. We recently revised our policies here so that when you submit a product idea through our website, we will periodically update you on the progress of your idea. If your idea is not right for us at the current time, we will inform you that your product idea submission is no longer being considered. If your product idea submission makes it to production, we will offer you the chance to test the beta version of the part (assuming both parties agree to the terms). This gives you the ability to not only say you came up with the idea, but also get the product before anyone else has the chance to buy one.

In the case of the TMIC, azmavhockey3 will be getting the final version of the TMIC a full month before anyone else because of his idea.

If you have an idea on how to improve this process or the product idea submission process, feel free to email me.


Aftermarket Parts and your Warranty

Now that our CorkSport Power Series Short Ram Intakes for the 2.3L DISI turbo-charged engines are 50-state legal (Press Release), I would like to revisit a past blog post as I think it is important for every car owner to understand.

A little over a year ago, we put a blog post on our webpage that outlined some of the laws and tips regarding your vehicle’s factory warranty and aftermarket parts you put on your vehicle. The Magnuson-Moss Warranty Act (US code – Title 15, Chapter 50, Section 2301-2312) was put in place to make it illegal for your dealer to void your warranty just because you put a non-OEM part on your vehicle (see SEMA Article). However, if you bring in your vehicle for a warranty claim, and it was obvious that the aftermarket part caused the issue, then you are out of luck.

The best way to avoid an issue is to have a good relationship with your dealer and to know in advance how accepting they are of vehicle modifications. Even though you have the law on your side, if they are not accepting of your vehicle modifications, you may want to find another dealer. No one wants to spend time dealing with a lawsuit or fighting over something that you can just as easily avoid in the first place. However, if you do run in to the unfortunate event where you believe that your dealer has wrongfully voided your warranty, you can contact the BBB Auto Line at 1-800-955-5100.

Please note that improper installation of any factory or non-factory parts that cause damage to your vehicle, are not covered under your warranty. Also, driving through water deep enough to cause water to be ingested into the engine will not be covered even with the factory intake installed.

If you have a specific question or concern about a CorkSport product, feel free to call us at 360-260-2675 or email and we will be happy to answer your questions.



I have been one of the Product Development Engineers here at CorkSport for roughly nine months. During that time, I have helped complete projects that were already in the works before I was here, completed projects on my own, and have started projects that are still in the development process. One project that I have been working on (other than physical part development) since I started here has been getting some of our parts California Air Resource Board (CARB) approved. After nine long months, I can now check that off my to-do list (at least for a few of our parts).

Our 2010-up Mazdaspeed 3 Short Ram Intake (SRI), 2007-2009 Mazdaspeed 3 SRI, 2006-2007 Mazdaspeed 6 SRI, and our 2007-up CX-7 SRI will now be CARB certified. This is the full intake kit that consists of the filter, MAF housing, silicone couplers, and turbo inlet pipe (TIP) as shown in the picture below. In the next few weeks we will be receiving a legal Executive Order (EO) number assigned to these intake packages. That EO number will be affixed to the intake system which will designate it as CARB approved (50-state legal).

If you already have our intake system for one of these vehicles, DO NOT WORRY! No, we can’t legally send you a sticker to put on your intake, but when you go in to the smog check station, they will look up our intake and verify that you have the same intake system on your vehicle.

The process of getting a performance part CARB certified is lengthy and time consuming, but we feel that making parts that are legal in all 50 states is very important.

Feel free to contact me if you have any questions!
