These PERRIN hoses have been designed to be real smooth on the inside with a significantly larger internal diameter when compared to the OEM inlet. The OEM inlet has pleats which can slow the air flow. The smooth design lets the turbocharger inhale more air which makes for an increase in horsepower, decreased spool time, improved acceleration, and increased throttle response.
The PERRIN Inlet is constructed and reinforced with stainless steel support wire that is embedded within the silicone layers. The support adds rigidity, and prevents the hose from collapsing if you were employing a larger turbo, running more boost, or running a restrictive intake.
