The PERRIN Turbo Inlet Hose removes a large leak the factory designed into the turbo. Fixing this leak reduces how hard the turbo works to hit the desired boost level. This added efficiency adds more HP and allows custom tuners to increase boost levels at higher RPMs, adding even more power!
The PERRIN Turbo Inlet Hose has a 3.0" internal diameter compared to the 2.6" 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 Turbo Inlet Hose is perfectly smooth on the inside. The OEM turbo inlet has sharp bends, corrugated ribbing, and strange pockets, all of which disturb airflow. The PERRIN Turbo Inlet Hose is much smoother, with more gradual bends toward the turbo making for less restriction leading to increased horsepower and improved acceleration.
The PERRIN Turbo 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.
