Perrin Front Mount Intercooler w/ Boost Tube Piping Kit 2015-2021 WRX

Swap out your overheated factory top mount intercooler for the PERRIN Front Mount Intercooler to get the most out of your turbocharged WRX. Add power and a new bold look all in one. The dyno graph was pulled from the testing we did comparing the OEM Top Mounted Intercooler and the PERRIN Front Mount Intercooler. We had the car all set so we could do these tests back to back with only a couple minutes between runs. The test compares the small stock TMIC to the huge PERRIN FMIC, and you can see there is 10-18WHP and 10-15ft-lbs of torque gain! Part of the reason for the gain is that the intercooler is less restrictive and also cools the charge air better. In this case, the PERRIN FMIC knocked off about 40F from the intake charge temperatures!

The most important part of any intercooler system is the core. The core cools the charged air on the way to the engine. The factory Subaru tube and fin intercooler was designed to be easy to manufacture, but is not good for performance.

Our testing has shown the optimum core design is the 3/8” bar and plate style that has a 3/8” charge air and ambient air path, instead of the common 1/4” size. The PERRIN bar and plate core design is much more durable than tube and fin with the ability to withstand rocks and other debris, which may enter the scoop. The PERRIN intercooler core is 28” long x 9.25” tall x 3.5” deep with a volume of 906.5 cu-in. giving the PERRIN Intercooler the best overall design for cooling and pressure drop!
