Perrin Blue Turbo Inlet Hose for Legacy GT / WRX / Outback XT / STi / Forester XT (perPSP-INT-421BL)

The PERRIN Turbo Inlet Hose will enhance airflow, boost horsepower, and add flair to your engine bay.

Silicone technology allows us to design a turbo inlet hose that is better in all aspects than the OEM part and increases your engine's horsepower and performance. The PERRIN Turbo Inlet Hose is perfectly smooth on the inside and has a significantly larger internal diameter than the OEM part. The increased airflow by removing the pleats found in the OEM hose makes more horsepower, decreases turbo spool time, improves acceleration, and increases throttle response. The PERRIN Turbo Inlet Hose is reinforced with a stainless steel support wire 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. Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning!

The PERRIN Turbo Inlet Hose is the only turbo inlet hose on the market to include an OEM-lie connector that does not require defeating the emission control device. Other turbo inlet hoses included a metal connector to join the turbo inlet hose with the intake. The PERRIN design has been further improved with the use of a glass-filled reinforced nylon coupler, allowing for an even smoother transition from intake to turbo inlet hose while also maintaining rigidity and strength. Also, the PERRIN Turbo Inlet Hose is perfectly smooth inside and has a significantly larger internal diameter than the OEM part. The increased airflow by removing the pleats found in the OEM hose makes more horsepower, decreases turbo spool time, and improves acceleration. The PERRIN Turbo 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 OEM part has a tendency to wear down and tear over time. The wire-reinforced silicone in the PERRIN Inlet Hose is much more durable. This unique PERRIN Turbo Inlet Hose has a machined aluminum insert that is bonded into the layers of silicone, giving you a solid blow-off valve hose connection and making the installation go even more effortless. All spigots on the PERRIN Turbo 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.
