Subject: Re: Removal of the emissions air tubes from the exhaust manifold by Matatk on 2009/11/29 23:13:20 Off an ebay auction: Either m18 or m22. These are AIR block-off plugs for your '96-'97 LT1/LT4 Camaro/Firebird, LT1/LT4 Corvette or LT1 Caprice. The set consists of two block-off plugs to remove the AIR system from your car. These plugs are machined from billet steel. You won't find a nicer plug. Note: These are M18 x 1.5 plugs that fit *MOST* '96 - '97 LT1 cars. However, it's possible that some '96-'97 cars will require the larger (M22 x 1.5) plugs. Although most '93-'95 cars require the larger (M22 x 1.5) plugs, some "oddball" 1993 and 1995 cars may require these smaller plugs. These plugs will *NOT* work on cars that require the larger (M22 x 1.5) plugs. Please measure the holes in your manifolds/headers before purchasing these plugs. In order for these plugs to work, the inside diameter of your header/exhaust manifold holes must measure roughly 11/16". |
