I'm at 81,000 miles on my Ram and I don't know when to replace them or what brand to use
It isn't that bad... takes about an hour or so(I have replaced alot of Hemi spark plugs).There's 16 of them so be sure it's worth the effort and money, it's around $150 for all the plugs. Turning yourself into a contortionist and busting your knuckles, priceless
oopsOkay thanks guys I couldn't find my owner's manual that's why I was asking
