best spark plugs to use?
The way I see it...
"No jap. **** in my car IF I can help it! " .... which you CAN! Yes AC Delco is more expensive but do it for the well being of AMERICA! Show you love your country and your car. Don't give it the enemies product!
Best of Luck.
NGK TR-55's in the standard configuration is a great setup....I actually would prefer to change the plugs more often than not, gives you a good clue as to whats going on in your engine.
