Figure at 68K its time to change the spark plugs on my truck.what are some good spark plugs to go with? on my dragster we use NGK and have had great success with them. Are they good on trucks? i know there are other brands out there AC Delco etc.So what do you guys use for spark plugs?

 

NGK tr6
Bottles are for babies and my baby loves it.

 

I was using ngk's and then someone suggested running autolites.. im trying those out so far no problems with either plugs

 

If your N/A, go with NGK Tr55's stock gap or a bit less. All I've ever used is NGK's, but I've moved from tr5's to 55's, to 6's when I was spraying. The lower the number, the hotter the plug.

 

TR6 would prolly be too cold i would recommend the 55's grey silver doesnt count with the size shot he is running

 

I went with the TR55 i like them seems like my truck starts up alot easier now.also i know i cant feel any performance gains but my throttle response feels a little better but thanks everyone for the help i was clueless on plugs for my truck.
