PERRIN Performance™ is the leader in WRX top mount intercoolers.

The huge 20 x 7.5 x 4 core creates an enormous surface area for a higher cooling capacity reducing intake temperatures and increasing oxygen density in the air charge.

The PERRIN™ Performance bar and plate core construction nets a larger over all surface area when compared to competitive tube and fin designs. The PERRIN bar and plate also has a higher resistance to damage from debris entering the hood scoop.  New cast aluminum end tanks offer smooth flow   and less pressure drop then sheet metal end tanks with sharp bends.

The PERRIN™ Performance top mount intercooler retains the stock bypass valve mounting flange allowing the tuner to use the stock blow off valve or any direct replacement blow off valve. The PERRIN™ top mount intercooler will work with almost all aftermarket turbos on the market today. VF30, VF23, VF22, and PE series turbo chargers are wonderful compliments to our intercooler.

The PERRIN™ top mount intercooler for the Subaru WRX includes a high flow silicon throttle body coupler and Y pipe.

The PERRIN™ Y hose will increase airflow over stock intercooler hoses with redesigned air passages insuring equal boost to all areas of any top mount intercooler. The non-corrugated, smooth finish will increase boost response and horsepower.

PERRIN™ intercooler hoses are made of high strength, reinforced silicone hoses, which resist high temperatures and boost pressure. Hand made and inspected to embody reliability and quality. Produced in a high gloss red finish, simply rinse with hot soapy water to return showroom luster.
