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.

Mishimoto 2010 STI
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.

Interested in purchasing our 2015 WRX cat-back exhaust? Check out more details on our product page linked below!
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.

We've shared a ton of teasers that show our awesome charge-pipe design for the 2015 WRX. Now it is time to show you how this component came to life.
First, take a look at the factory-equipped charge pipe.

Interested in purchasing our 6.4L coolant filter kit? Check out our product page for more information!
We mentioned in our 6.0L coolant filtration thread that we would be tackling the 6.4L as well. Let's take a look at some of the components our team has been putting together for the 6.4L kit.
Although the 6.4L does not seem to be as susceptible to buildups as is the 6.0L, a coolant filtration setup is certainly still a worthy investment in preventive maintenance.
So let's get started!
Filter Housing
We'll start with the filter housing. As mentioned in our 6.0L thread, we developed a housing with a wide range of adjustability that could be utilized for a variety of kits. This housing is shown below.

Interested in picking up this awesome Mustang EcoBoost Intercooler? Check out our product page for more details!
With nearly a 30-year gap between the old and new turbocharged 4-cylinder Mustang, some things are bound to change. The new Mustang features many interesting advances in technology, including direct injection, a twin-scroll turbocharger, a DOHC cylinder head with variable valve timing, and a newly designed intercooler. The 80's model featured a top-mount intercooler that was fed cool air through a functional hood scoop. This was pretty slick stuff for the days when the Walkman revolutionized how we listen to music, and "the Clapper" paved the way for a new level of laziness.
The new Mustang features a very efficient front-mounted intercooler that fits right below the radiator. A fresh stream of airflow passes through

Interested in picking up this awesome catch can kit? Check out more details on our product page linked below!
When we left you last time, we had equipped our Mustang up with our prototype dual-can setup, and we sent the vehicle out for some road use. Since we would be testing other components (intake and intercooler) at the same time, dyno pulls would also be conducted with this setup installed.
After just 300 miles of road use, this is what we found.
