Some people just wont listen. I do not know why they ask for advice and refuse to take it. If you want platinum plugs just go buy them. I have had no issues with the stock plugs and I race my car. Its all a matter of preference but at least get the stock equivalent. In this case a copper clad plug.
Thanks for the info on the E3 spark plugs. Will change them out this weekend. I don't have any other plugs or the time to change them out before leaving for the track tonight.
