Perrin Performance - 3.0" Turbo Inlet Hose - 04-14 Subaru WRX/STI
The PERRIN Turbo 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, improves acceleration and increases throttle response.

Just for Big 3" Turbos

Stainless Steel 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 bond 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 ont he 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 400 degrees F) which will withstand engine bay temp found from normal driving to extreme racing conditions.
