With positive horsepower data and an impressive intake tone, all our goals were met, so it was time to move towards project completion. We set out to finalize the design, finishes, and construction of our production units and, as you can see below, they turned out quite well. This will be offered in three finishes including polished aluminum, wrinkle-red, and wrinkle-black. Each kit includes an intake pipe with air straightener and MAF housing, a Mishimoto high-flow air filter, a heat … Continue Reading ››
Finally, we come to the sound improvements that the Mishimoto intake provides. Everyone loves a nice throaty intake sound, almost as much as the intoxicating burble from a set of unequal-length headers. During our many dyno pulls, collection of data for decibel strength was something we wanted to explore and compare between the factory design and our design.

It was now time to see the fruits of our labor and collect some data with our revised design. Our poor STI was once again strapped to the dyno (This is what it’s built for, right?) and endured pull after pull as we evaluated power, AFRs, sound improvements, and durability. Weeks of testing resulted in a design that not only pleased our engineers, but also excited them to see some enthusiasts install and use it. Bolting on 25 whp has … Continue Reading ››
With our initial designs complete and fully assembled, the engineers were ready for testing. We strapped our STI to the dyno and began making some initial pulls with the car completely stock and using the OEM intake. We were averaging upper 250s to lower 260s at the wheels, which was what we expected from this car. After having some fun we removed the factory intake system, including the airbox, air induction tube, and MAF housing. We bolted on our first … Continue Reading ››
Here we are at round two of product development. The shear, brake, and welder had quite a workout as our team set to work on developing two very different prototypes for testing.
The first design was rather unique and emulated the factory system quite well. This large, box design used a standard panel filter and pulled cold air from the fender/wheel-well area. This unit was very well designed and would keep your engine bay appearing OEM while providing improved power and … Continue Reading ››
