UNUSED Motion Performance Cold Air Box Inlet Duct. Made for MP Phase III/L88 type hood design as used on 1968 - 1969 Corvettes. This hood design was made for most of the Chevrolet vehicle line in the early 1970s to early 1980s. Is very rare. NOT designed for GM hoods!

Fiberglass construction. Meant to be installed with fiberglass panel bonding adhesive to the underside of any of the MP hoods. Works with bolt on or hinged applications. Aligns over center of carburetor for air filter. Can use GM L88 parts to replicate the L88 hoods with ducts from 1967 thru the 1970 ZL1. Can also use a 14" diameter filter element for a custom installation.

Duct measurements are 27" long and 21 3/4" wide. 12 3/4" hole size with 15" diameter fitment for foam/screen or 14" filter element.

I bought this Duct and a MP Phase III hood for my 1963 Corvette in 1973. No breakage. Duct has never been installed or used. Has been in storage since purchase. Is DISCONTINUED.

Review attached photos for other applications for this hood and Duct design.

Prefer NOT to ship large fiberglass part!

Price negotiable.
