Ok first off I seen that spark plugs are $3 off a pack of 2 so I'm gunna replace them but I was wondering if i should go with the stock 606's or if i should go a heat range higher (the only thing I have done to my car is put a 2 1/2 dp with a high flow cat and a drop in k&n filter don't rag on me it works fine) So anyway if I should go a heat range higher what plug are they. My second question is how mutch are the gaskets between the TB and the UIM. I finaly cleaned mine as best I could without takeing it off and it starts sooooo much smother
