spark plugs |
Subject: spark plugs by tjpreul on 2008/9/17 1:34:36 I am currently replacing the plugs '92 LT1, engine code P. The service manual specs a flat seat plug with gasket P/N AC904. The plugs that I bought are a tapered seat Bosch P/N 4205. I want to make sure that they will seal without hurting the heads. |
