Mishimoto Subaru STI Performance Air Intake

As noted earlier in this article series, we would be tackling a race intake system to go along with our bolt-on unit. So what makes the race system different? For this particular system we are using a larger-diameter intake pipe with a larger MAF housing. This means greater intake flow, but it also means it will no longer function with the factory tune. This system is meant specifically for drivers who want aggressive professional tunes so they can take advantage of airflow modifications such as larger turbochargers and high boost pressures.

Because the 15' model shares the EJ from the previous generation, we would be using the same intake pipe and filter as we did with our 2008-2014 kit. This unit is shown below.

So, all we truly needed

An Interesting Discovery

At this point, our intercooler project took an interesting turn. We wanted to develop a cooler, including going through the process of 3D design, and working up a prototype unit. That said, we had a new idea to get some early baseline testing for core design.

After swinging by our sample room, we retrieved the cooler shown below.

Last time we covered the design of our intake pipe and left you with a look at our airbox design in the form of a rendering. It's time to show you how we developed this component.

First, we started with some steel and began selecting mounting points for attaching our box. Once we found these points, we pulled out the welder and began fabricating a prototype.

Crash Beam Fabrication

After an unsuccessful test fit of our existing bumper beam on the 15', we started from scratch to create a beam specific for the 15' chassis. First we hacked off the end tanks of our cooler so we were left with a bare core. This would provide some freedom to design our crash beam and later work on the end tank direction. Next we cut out some new mounting plates and fit them into position.

After developing a highly successful, direct-fit catch can setup for the 2015 WRX we turned our attention to the previous generation. Our next target would be the 2008-2014 WRX and STI. At this point, Mishimoto still owned a 2010 STI, and this project would be our last for our shop vehicle.

With the stock unit out of the way we could begin developing our intake piping. We would be starting at the turbocharger and working outward to an airbox near the stock location.

Using the dimensions from the stock unit, we developed a 3D model of an inlet hose that would be constructed from a silicone material. After completing the model, we produced a unit using our 3D printer.

As promised, we hit the road to begin testing our prototype designs. Our first round of testing was purely to evaluate the tone and sound level of the exhaust.

What are we looking for?

• Rich tone
• Little to no rasp
• Minimal highway drone
• Noise amplification from one-half to full throttle

As you know, the FA20 utilizes an equal-length header, which means that the traditional Subaru rumble is likely to be lost. Either way, we would be looking for a nice tone that would be acceptable for daily use.

Our first road test utilized our smaller, round style muffler.
