1973 - 79 Pontiac Grand Prix Grand Ville 350 400 455 Fresh Air Hose 4"


This item is out of stock



OEM style 1973-79 Pontiac Grand Prix Grand Ville Bonneville 350/ 400 / 455 Fresh Air Duct. This is the correct style 4" fresh air duct that was used on all Pontiac A/B/C bodies from 1973-1979. It is new and has never been used. The hose features a 4" diameter opening on both ends with formed metal locking clips. Unlike the cheaper plastic clips (and even cheaper flex hose with no clips), these are as close to the OEM fiber air intake hoses as possible. The 4" vinyl hose covers the spiral wrapped insert - providing resistance to moisture, as well as the strength required to bridge the gap between the air cleaner inlet and fender mounted fresh air duct. It installs on the either the oval to round adapter, or round air cleaner inlet and connects to the elbow duct on the inner fender well.

Specifications: These hoses are approximately 12" in the relaxed position and extend up to 18" to fit a myriad of requirements. Since they feature metal spirals, they will retain their uniform diameter throughout the hose once installed.

These parts have completely disappeared from the production process - we have a very limited number of these available.
