    The NGK's are/were the same as the AC Delcos. my stock plugs had Acdelco on one side of the plug and NGK on the other side. posted pics of it somewhere on this blog a while back. I like NGK's too. run them in my wifes car and my commuter

    justin price.....as mentioned in the Thread here.....Going with and Staying with Factory/OEM Plugs is the Way to Go is with...and the Plugs I run in my 5.3 Liter are the......A/C Delco Iridium Tip Spark Plugs....

    I would also mention, that the Spark Plug Fastener Tightening Spec's. are 11 lb ft and also make sure to use some.....Anti-Seize on your Spark Plugs, is Particularly Advisable with Engine Head's made of Aluminum, and use Dielectric Grease, Use your finger to Spread the Dielectric Grease around the Ceramic Portion of the Spark Plug. This will Help Keep a Dry Environment for the Spark Plug to Wire Connection. The Grease will also make Re-Installation of the Plug Wires Easier.
