The PERRIN inlet hose is also able make more HP, quicker throttle response, and improve acceleration! By removing the pleats found in the OEM hose, increase the internal diameter, and mirror smooth finish reduce intake restriction. Thus more HP. Check out the charts page for dyno results! (Will be there shortly!)
Also, PERRIN has an advantage over other brands. Our 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 for1-1.5 hours and no extra parts.
