Perrin Turbo Inlet Hose - Black - Subaru STI (2004-2021)

The PERRIN Turbo Inlet Hose, made with advanced silicone technology, outperforms the OEM part with a smoother, larger interior for increased airflow. Removing OEM pleats boosts horsepower and improves spool time, acceleration, and throttle response. A stainless-steel support wire adds rigidity and prevents collapse under high boost or with restrictive filters.

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.

The PERRIN Turbo Inlet Hose is the only turbo inlet hose on the market to include an OEM-like 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 a glass-filled reinforced nylon coupler, allowing for an even smoother transition from intake to turbo inlet hose while maintaining rigidity and strength.

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, and improves acceleration.

The PERRIN Turbo Inlet Hose features a stainless-steel support wire embedded in silicone for added rigidity and to prevent collapse under high boost or restrictive filters. Unlike the OEM hose, which wears and tears over time, PERRIN’s wire-reinforced design offers much greater durability.

The PERRIN Turbo 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 making installation go even easier.

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.
