Perrin Turbo Inlet Hose (3" / Black) - Subaru WRX 02-07 / STI 04-21

Description

The PERRIN Turbo 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.

Smoother Airflow
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.

No Tuning Required
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! Confirm any tune or recalibration you add is specific for ALL modifications added to the vehicle.

Just for Big 3" Turbos
The PERRIN Performance 3" Turbo Inlet Hose is specifically designed for turbo charger upgrades with 3" inlets. PERRIN is your only option to avoid constructing your own intake system and is compatible with any replacement intake system which will work with the stock inlet hose.

Stainless Steel 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 that is bonded into the layers of silicone, giving you a solid blow off valve hose connection and making the installation go even easier.

Large High Flow Spigots
All spigots on the PERRIN Inlet Hose are 1/2"ID for maximum flow from crankcase 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.
