About this product

Part #: EVO1206

The Evolution of cold air intakes is here. The Evolution cold air intake system by Injen Technology is the next generation of performance intake systems. The EVO1206 is specifically engineered for the 2015-16 Subaru 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. They include stainless steel hardware and automotive grade urethane couplers. No cutting or drilling required for an easy installation process that does not require aftermarket tuning for exceptional HORSEPOWER and TORQUE GAINS. The EVO1206 was precisely tuned and tested on our in-house dyno to replicate stock fueling while increasing horsepower and torque. The system was carefully designed utilizing the latest in CMM Laser Scanning hardware - SolidWorks 3D CAD Software – and finally prototype tested after being printed on one of our state of the art 3D printers – and this is all before ever being released for production! The Subaru STi ECU is very sensitive to modifications and will not accept most aftermarket intake kits without the use of an additional tuner. This is not the case with our Evolution cold air intake. We utilize an aluminum tube that incorporates our patented air fusion and 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, redesigned ram air scoop, a massive 360° SuperNano-Web dry air filter, and a built-in Filter Monitor for quick and easy filter inspections. Every Injen Evolution air induction system utilizes Injen's proprietary SuperNano-Web dry air filters. Don't just take out word for it, every intake system that Injen Technology produces is 100% dyno tested in-house. The Evolution can't be stopped…..

What made you choose this particular product?
Good pricing on eBay
Is this your first time buying from this brand? Did you consider other brands?
First time I've purchased Injen. Would recommend if you're on a budget, but don't want the no-name eBay special.
Was it easy to install? Any installation tips that will help others?
Installed by myself. You'll need some security screwdriver bits. A snaking socket wrench extension is recommended, but not required.
Once you've had a chance to use the product, did it meet your expectations?
Induction sounds are immediately more apparent. My stock diverter valve started whistling shortly after installation, so plan to upgrade that around the same time.
Any additional comments?
The cone filter rubs against the included air scoop, causing the filter to get a bit scraped up during use. I'm not worried about the filter getting damaged badly, but I was a little disappointed with the fit, hence a 4 star review.
