I am getting ready to change mine and was wondering what eveyone else uses. Thanks.

 

I run Autolite 3923's, but have heard good things about NGK ZR5F-11 plugs.

 

Rapid fire spark plugs from autozone. I find my truck idles very very nice on these. This is not the SPLITFIRES - But rapid fires. The tip comes to a star shape. At least they used to. I didnt check this last set but I really like them....



They are made by ac-delco



You will find everyone has an opinion on this topic... But this is what works well for me...

I have had them in all my cars for years now.. No problems so far....


Good luck

 

Thanks guys!!
