1970-72 Oldsmobile Cutlass 350 W-25 OAI Air Cleaner Top Assembly

Complete OAI top assembly includes the vacuum controls, filter and hold-down components.

This W-25 outside-air-induction top assembly is a reproduction for your 1970-72 Oldsmobile Cutlass with a 350 engine and four-barrel Quadrajet carburetor. It includes the vacuum valve, air-filter top, vacuum lines, flapper door, springs, valve-cover spring retainers and an air filter. For an OAI conversion, reuse the original four-barrel air-cleaner base and install the valve-cover retainers and hold-down springs to position the assembly against the hood seal. The 350 version uses a foam hood seal 3/8 inch taller than the 455 version. Retaining that height difference provides the correct 350 OAI configuration and factory-style appearance; this SKU should not be treated as an identical 455 assembly.
