The PERRIN inlet hose has a 3.0" internal diameter compared to 2.7" found in the OEM part. This allows for a greater amount of air to smoothly enter your engine with virtually no restriction. This larger diameter will easily support all bolt on modifications and increased boost levels.
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 collapses when used with restrictive filter elements and high horsepower setups
