Injen Evolution Cold Air Intake - 2015-2017 Subaru STI

Improve airflow to breathe power into your STI

If you’re longing for more power then give your engine the tools it needs with Injen’s Evo cold air intake system. Specifically made for the 2015-2017 Subaru STI 2.5L engine, this intake maximizes your Subie’s inlet airflow giving your motor and turbocharger all the air it can handle for some big power gains.

Increased torque and horsepower performance right out of the box

An awesome feature of this intake is that it doesn’t require aftermarket tuning and is designed to work with stock calibration. The intake tube has been tirelessly tested to provide safe and reliable fuel trim levels. You won’t have to cut or drill to get this installed on your Subie and Injen’s dyno testing has proven you can expect performance gains of up to +26 horsepower and +34 ft/lbs of torque! On top of all that it adds a more aggressive look to your engine bay and has a great OE fit.

2-piece box design with quality air filter and intake tube

This intake uses a 2-piece box design to integrate Injen’s boost plenum, ram air scoop, and SuperNano-Web dry air filter. The huge air filter increases airflow volume to get as much power as possible to your turbo and seals to prevent leaks. There’s also a clever built-in Filter Monitor allowing you to perform painless inspections.

Injen hasn’t missed any details with a professionally rotomolded housing constructed of cross linked high density polyethylene. The intake tube is 6061 aluminum with a wrinkle red finish and a spot for your MAF sensor. The band clamps are stainless steel with an inner protective liner to the reinforced silicone coupler. This intake is designed for durability and power!
