Injen 2015 Subaru STi 2.5L 4 Cyl (Turbo) Wrinkle Red Cold Air Intake w/ MR Tech and Heat Shield

When you're looking to get more out of your 2015-2017 Subaru WRX STI, especially when it comes to unleashing its turbocharged 2.5L engine, a well-designed cold air intake can make a notable difference. This Injen SP Series cold air intake is built to help your engine breathe easier, allowing for improved airflow that translates into more horsepower and torque. It's designed to replace the restrictive factory airbox, giving your engine a smoother, more direct path to cooler air.

The heart of this system is the 6061-T6 aluminum intake tubing, which Injen uses to create an uninterrupted path for air. This intake features Injen's patented MR Technology, which is a tuning process that helps ensure safe air-fuel ratios while maximizing power gains. You'll also find a custom-designed heat shield included, which works to keep hotter engine bay air away from the intake filter, ensuring your engine gets the coolest air possible. The system comes with a fully serviceable SuperNano-Web dry air filter, known for its ability to capture fine particles while allowing for substantial airflow. Expect an improved, more aggressive engine tone under acceleration, letting you hear the performance improvements.

This Injen SP Series intake is designed as a direct fit for your 2015-2017 Subaru WRX STI, meaning it installs without needing additional tuning. It's made in Pomona, California, and comes with Injen's limited lifetime warranty.
