Stillen Cold Air Intake with Heat Shield
STILLEN has decided to step into the Subaru WRX performance market with our performance cold-air intake system. They replace the restrictive factory air box with a genuine K&N reusable hi flow conical air filter. Replacing the factory airbox and intake tube STILLEN is able to achieve a gain of 30 wheel horsepower.
The filter sits behind a laser cut, CNC formed, lightweight aluminum heat shield. The purpose of the shield is to keep the cold air entering through the factory intake duct into the area surrounding the air intake. This creates a cold air path which helps to achieve the 30 horsepower gain.
During development of the 2015 Subaru WRX cold air intake STILLEN utilized one of our team members vehicles for the durability and data acquisition testing. After thousands of miles of trouble free driving we are confidently able to say that the STILLEN FA20DIT cold air intake will not set any check engine lights.

Throws the check engine light, will need a tune.
Consider your options
Pipe fitment is absolutely terrible. The installation required the anchor bolt flange to be drilled out in order to align the pipe with the lower stock piping. The sound derived from the intake is nice but not worth the hassle of 'making' it fit. My advice is to carefully weigh your options...
Best bang for your buck!
Overall, in my opinion this is the best Intake to run if you're not wanting to add a tune. One of the few systems that includes the heat shield at no additional cost. Stillen are heavy hitters with the Nissan community and now is a great chance for Subaru owners to get top notch parts at an entry level cost! As always, subispeed thanks for another great product, fast shipping and excellent customer service! (Consider me for that 100 gift card so my wife doesn't get so mad when I order from you guys)
