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.
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. 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.
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. 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.
The PERRIN turbo inlet hose is the only hose on the market today that does NOT require the removal of the intake manifold! This cuts the install time from 4-6 hours down to just 1 hour! We achieve this by changing the placement and type of spigots used. This design also means NO more rerouting of crank case vents and hoses! No need to purchase extra gaskets or deal with fuel and coolant spills!
Fits: all 04-08 Subaru Forester XT models.
