sparkplug change! do i have too?

[mxblaster83]

ive been reading a bunch online about people changeing thier sparkplugs
at 30k and saying they look brand new.

my question is how importent is it to change them.
or can i get away with without???

Not sure if the new Truck uses the copper (I assume yes if a 30K interval is called for) but what happens is the Gap starts to open up over time and at that 50 k Km mark you will find they are probably a good 5 thou too big at that point, thats my experience. 65-70 Bucks and some quality time spralled over your engine and its done, the more times you do it the faster you get.

i believe for warranty reasons it should be done at 30,000

I'd pull the easiest one to get to and check it. If it looks/gaps like new i'd leave'em in, and check again at 45k mi. No sense in replacing them if they're still good.

Simple, if it's in your owners manual re. maintenance schedule then do it.
