This is just an FYI, I posted that my w201 had idle problems after changing my transmission fluid and it turns out that it was a spark plug wire. Well, it did it again and I took the wire off the plug and realized that the rubber part inside the boot was torn off. Anyways, I did not know Bosch wires had a LIFETIME WARRANTY

. I called autozone and they gave me a brand new set and took the old ones back after I had them for 2 years and said that I can do this forever as long as I had Bosch wires. I did not know this at first, I just saved myself $100+ tax for every 15,000 miles!

I need to see what else I have that has a lifetime warranty, this is great!
