Wow, seems like a lot are having problems with the headers.I have 2003 s, I also put headers and I keep getting the cel. I put in spark plug non fowler p/n 42002 last weekend and drove it about 100-200 miles, so far the light has not come back yet. you can get this part in any parts store. you need to buy 2 sets and drill the other one. you can google it and get more information or you can pm and i will send you more info.
