THE plug for GM 3800's

If you have a 3800 (GM motor), this is the plug to buy. These plugs give a smooth idle, good performance and gas mileage, and last 25,000+ miles.

      A:

      Hi Dan, I'm happy to help you! You'll need 6 of these NGK V-Power Spark Plug - Part No. 3951 for 1996 Chevrolet Blazer 4.3L. It is essential to tighten a spark plug to the specified turning angle or torque setting. First, screw in the plug finger tight until the gasket meets the cylinder head. Then seat the plug/gasket with a torque or turning an angle wrench as specified in your owner's manual.
