Subaru Turbo Inlet Hose
Silicone has been used for years in Aerospace and medical equipment,
Silicone is now seeing a resurgence as a durable and superior material in performance motorsports. Silicone technology allows us to design a turbo inlet hose that is better in all aspects than the OEM part and increases your engines horsepower and performance.
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. 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.
08+ Specific Design
The PERRIN inlet hose for the 08+ WRX and Legacy GT is the only inlet hose specifically made for this car. This is not just the STI version adapted to fit like other inlet hoses. This is specific to the engines with the plastic intake manifold with specially designed spigots and BOV fitting.
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.
