Ranger Posted March 11, 2011 Report Share Posted March 11, 2011 I'd stick with what it came from the factory with. They lasted 125K. Link to comment Share on other sites More sharing options...

KHE Posted March 11, 2011 Report Share Posted March 11, 2011 Use the AC Delco dual platinum tipped plugs as specified in your owner's manual. Also, it might be a good time to change the distributor cap and rotor.

cdgrinci Posted March 11, 2011 Report Share Posted March 11, 2011 I've got to echo the call of OEM's A/C Delco platinums. Chuck '19 CT6, '04 Bravada........but still lusting for that '69 Z-28 Link to comment Share on other sites More sharing options...
