Give your Subaru WRX STI that added punch you crave with the EVO1206 Evolution Cold Air Intake System by Injen Technology. The EVO1206 is specifically engineered for the 2015-17 Subaru WRX STI with the 2.5L engine. Every EVO1206 cold air intake is made in the USA from cross linked high density polyethylene for extreme durability. No cutting or drilling required for an easy installation process that does not require aftermarket tuning for exceptional HORSEPOWER and TORQUE GAINS right out of the box!
The EVO1206 intake tube is made from 6061 aluminum and coated in a fantastic wrinkle red finish. The intake tube was then precisely tested and tuned on our in-house dyno to replicate stock fueling while increasing horsepower and torque. The Subaru WRX STI ECU is very sensitive to modifications and will not accept most aftermarket intake kits without the use of an additional and costly tuner. This is not the case with the Injen Evolution cold air intake. Our intake tube incorporates our patented air fusion and our patented MR technology to provide safe and reliable fuel trim levels, all without the use of an aftermarket tuner!
The EVO1206 system features our 2-piece box design that incorporates our boost plenum, our fully integrated ram air scoop, and a massive 360 degree SuperNano-Web dry air filter. Every Injen Evolution air induction system utilizes Injen’s proprietary SuperNano-Web dry air filters. Don’t just take our word for it, every intake system that Injen Technology produces is dyno tested in-house and those results are published for anyone to see.

6061 Aluminum Intake Tube:
The EVO1206 Evolution Air Intake System uses a custom designed and dyno-tuned, aluminum intake tube that utilizes our patented air fusion and MR technology to produce huge power gains while retaining an OE quality fit and safe fuel trim levels.
