Perrin Subaru WRX (02-07) & STI (04-17) 3" Black Turbo Inlet Hose

3" Turbo Inlet Hose

Silicone technology allows us to design a turbo inlet hose that is better in all aspects than the OEM part and increases yPerrin's engines horsepower and performance.

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, improves acceleration and increases throttle response.

The PERRIN 3" 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.

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.

Just for Big 3" Turbos

The PERRIN Performance 3" turbo inlet hose is specifically designed for turbo charger upgrades with 3" inlets. PERRIN Performance is yPerrin's only option to avoid constructing yPerrin's own intake system and is compatible with any replacement intake system which will work with the stock inlet hose.

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. Watch the Video.

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 Perrin's hoses are glass reinforced nylon (rated to 400 degrees F) which will withstand engine bay temps found from normal driving to extreme racing conditions.
