gunna change the spark plugs in my truck tomm..anyone use these plugs? if so how do you like them? any other ones yall use? lemme know and how yall like them also... also wondering about over gapping the plugs a little bit.. i did it in my ranger and it felt like it had some more pep to it... BTW i have the 5.9 360

 

Either autolite copper core 3923's at walmart, or champion truck plugs.

 

I am running NGK ZFR6F-11 plugs in my 01 5.9L and they do great! I have put the autolites in it before also, but I like these a lot better. It seemed to give the truck more pep.

 

I really like my Autolite copper plugs, have had 0 issues with them.

 

I hated the Autolites. After a month or so it didn't seem to run as well. I switched back to the Champions. I'd recommend staying with the Champions. I've never run NGK in my Dodge but they are awesome plugs in anything else I've run. So I'd try them if I was to try a plug other than Champion.
