A performance turbo inlet hose is a great modification, especially when upgrading a turbocharger or to a high flow intake system. Perrin’s turbo inlet hose for the 02-07 WRX & STI features 5-ply silicone construction with an internal wire mesh for maximum durability and rigidity without the added weight or heat retention of metal. Perrin’s full silicone construction is immune to heat soak and guarantees a smooth internal passageway, unlike the stock corrugated rubber inlet found on your stock Subaru. This allows for more intake air, ultimately creating better throttle response and more power. A stainless steel embedded wire system eliminates any change of collapsing. We highly recommend upgrading your inlet whenever upgrading your turbocharger as this will greatly ease the installation process of both components. The Perrin turbo inlet hose for the 02-07 WRX & STI is available in stock (2.4″) and 3″ diameter sizes for larger turbo upgrades, please choose accordingly.

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.
