My first post and I am looking forward to this site...alot!!!
I own a couple of GMC trucks.A 2011 2500 HD SLE 4x4 reg.cab with a Reading utility body & a 2004 3500 HD SLE ex.cab 4x4 cab and chassis with dump body.
My question is although the 2004 only has 37,000 miles I feel due to the age and the fact that I plow the truck I should change out the plugs.What brand should I use?My gut says stick with AC, but with all the new types of platinum etc. plug out now,I wonder if there is a better choice.
