The PERRIN inlet hose is able to make more horsepower, smooth throttle response and improve acceleration! By removing the pleats found in the OEM hose, increasing the internal diameter and combining a mirror smooth silicone finish reduces intake restriction. PERRIN has an advantage over other brands, their inlet hose is the only one on the market today that does NOT require the removal of the intake manifold! That is HUGE. Think about it, no fuel to drain, no water lines to remove, no gaskets to purchase, less nuts and bolts. A huge advantage if you do it yourself or pay a technician. Instead of paying for 4-6 hours labor and parts, you should only have to pay for 1-1.5 hours and no extra parts.
The 3" turbo inlet will NOT fit the factory turbo.
May require intake manifold removal for installation.
