Spark Plug Difference?

Sep 20, 2004 3 Replies

I bought a set of spark plugs for an 88 Sunbird 2.0 4 cyl. at Autozone..the guy gave me AC 44XLS..now that I've checked the manual...says AC 44XLS6.Could someone tell me if these should be ok in this eng. or should I exchange them..Thanks for all replies! Bobby



The 6 stands for factory set with .060 gap, AFAIK

Replier Mark said the same as the a/c delco website:

Plug 4 (what kind of a bizarre part number is that?) may be the same as 44xls - Check the plug and see if it says: "4", and nothing more.

41-819 SPARK PLUG, PLATINUM PLUG GAP .060 4 SPARK PLUG, RAPIDFIRE PLUG GAP .040 R44XLS6 SPARK PLUG, STANDARD PLUG GAP .060

Thanks Mark That makes sense 6..stands for 0.60.The AC 44XLS was factory set at

0.35..so I reset them at 0.60 ..before I installed them...so that would more likely make them the same then.Thanks for the info. Bobby
