PERRIN PERFORMANCE 2.4" TURBO INLET - 02-07 WRX, 04-21 STI, 04-08 FXT
Perrin designed their turbo inlet hose with a main goal in mind; to add performance and horsepower. These turbo inlet hoses compared to the OEM unit, are larger in diameter, and are designed to smooth out the flow path allowing your turbo to inhale more efficiently.
Furthermore, these are constructed from heat resistant silicone layers that have a stainless steel wiring structure for superior reinforcement. Expect increased spool time, throttle response, and increased horsepower with the Perrin Turbo Inlet Hose.
Smoother Air Flow To Turbo
The PERRIN inlet hose is perfectly smooth on the inside and has a significantly larger internal diameter than the OEM part. The increased air flow by removing the pleats found in the OEM hose makes more horsepower, decreases turbo spool time, and improves acceleration.
SS Internal Support Wire
The PERRIN inlet hose is reinforced with a stainless steel support wire that is embedded within the silicone layers. The support adds rigidity to the hose and prevents collapse when used with restrictive filter elements and large turbo applications running extreme amounts of boost.
Blow Off Valve Connection
The PERRIN inlet hose has a machined aluminum insert which is bonded into the layers of silicone, giving you a solid blow off valve hose connection and makes installation go even easier.
Large High Flow Spigots
All spigots on the PERRIN inlet hose are 1/2”ID for maximum flow from crank case vents and other vacuum connections. All connectors used on our hoses are glass reinforced nylon (rated to 400 degrees F) which will withstand engine bay temps found from normal driving to extreme racing conditions.
