So I got a notice from Onstar that my truck is approaching 100,000 miles. Me being the lazy MF that I have become in my old age call the dealer to inquire how much they charge to replace the spark plugs. Damn they must be on drugs!! $250.00 and that's just labor! Now I realize that they have to pay labor and keep the lights on but damn!!! So my question is do I need any "special" tools to replace the spark plugs in a 07 Avy 5.3? Is there anything I need to be careful of? I haven't replaced spark plug in a car in about 20 years but I'm sure the basics are still the same. Might as well replace the wires while I'm at it. Thanks in advance.
