Designed to maximize airflow and cooling for power-hungry applications, the Mishimoto 2015 STI Front-Mount Intercooler Kit offers superior performance for your 2015 WRX STI. Boasting a 28" intercooler core that's 3.5" thick, this kit can handle up to 600 whp or 30 PSI of boost pressure! Thanks to the cast end tanks, airflow is uninterrupted for improved cooling without pressure loss. Mandrel-bending and aluminum piping further guarantee maximum airflow, and specialized crash bars keep your factory fog lights intact. No cutting of the front bumper or other modifications are necessary, and two turbo outlet hoses support both stock and aftermarket bypass valves. Backed by the Mishimoto Lifetime Warranty, this intercooler is an ideal choice for your fully built rally car.
