PERRIN 3" Turbo Inlet Hose w/ Nozzle For 2015-2020 WRX




Improve airflow, increase horsepower, and add style to your engine bay with the PERRIN Turbo Inlet Hose. NO TUNING REQUIRED.

PLUG-N-Play Crank Case Vent Connector 

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. 

Smoother Airflow 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.
