I want to change the plugs and wires on my 2002 Chevy Silverado. It alomost has 100,000 on it. I don't want to pay 400.00 to let someone do it when I can change them myself for under $50.00.
 
If you can buy decent platinum plugs and good wires for fifty bucks then all the power to you. Sounds like the ones you're going to buy are cheap things. Remember you get what you pay for.

All you have to do is remove the plug wires from the spark plug and on the same cylinders coil assembly. Remove the spark plug and discard after inspecting it as this can tell you what's going on inside there. Then align the electrodes and gap it to the spec. Install into the hole and spin it in with your fingers or a vacuum hose until it bottoms. Then torque it in with the special spark plug socket you've already purchased. Redo for the other seven. Done except for the fuel filter.
