Don't buy them from Amazon. They sell counterfeit 41-103's. I had two sets wear out in 10,000 miles (and took a set of coil packs with them).

I almost purchased those ACDelco $18 set of plugs from Amazon, Ebay has them as well. I knew they had to be fake until I searched this great forum... Damn, I was right and can't save any money.

You can save money by using the parts store online discount coupon and look for the official AC Delco rebate. After all that I paid around $20
