The Elusive MazdaSpeed 3 Cold Air Box Has Arrived!

People have been hitting us up via every contact point possible: phone calls, emailing, Facebook posting, Forum chatting, and contacting us via our webpage to find out when the CorkSport Cold Air Box for the 2010 MazdaSpeed 3 Short Ram Intake will be available. I am proud to say that it is finally here.

Way back all the way to the beginning of February, we had a blog post outlining the details of the depth we go into when designing a Cold Air Box. After finalizing the design and getting a production part installed in our project car, I went out and did some extensive testing. Using a laptop, data-logging software, and lots of thermocouples, I was able to log temperature changes over time.

The delta temperature in the graph below is the temperature difference inside the CAB (right at the filter) versus the temperature directly outside the box (inside the engine bay). The red line shows the difference over time using the box right off the shelf. The blue line shows the CAB with fully taped and insulated connections (the SRI to CAB mating area) attempting to reduce heat soak even further. The green line shows the difference over time with the CAB fully insulated and a direct pipe running from the fog light opening to the CAB (simulating a CAI).

Each reading was taking in the same atmospheric temperature (+/- 2 degrees) driving the same route at the same time each day. The route consisted of highway driving (both at highway speeds, and stop and go traffic) as well as city driving.

As you can see from the graph, all 3 designs yielded roughly the same result of about a 35-40 degree decrease in intake temperature once the vehicle has reached operating temperature.

As a conclusion to this experiment, I can confidently say that our CAB for the 2010 MazdaSpeed 3 paired with our SRI can bring your intake temperatures down to the same temperature as you would see with a cold air intake, without the drop in pressure or any worry about driving in the rain.

As always, if you have any questions about the product, or if you want to know more about how the data was obtained or evaluated, shoot me an email.
