Perrin, a trusted name in the Subaru and Mitsubishi community offers a fantastic upgrade from your factory turbocharger inlet. We recommend using a small amount of silicone spray on the inlet to ease installation. Part Number: PSP-INT-401BK = Black PSP-INT-401BL = Blue PSP-INT-401RD = Red Warranty : 5 Year Manufacture Warranty Inlet Size : 2.4 Inches (61mm) Silicone technology allows us to design a turbo inlet hose that is better in all aspects than the OEM part and increases your engines horsepower and performance. 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, improves acceleration and increases throttle response. 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. Available in glossy black, red or blue.
