Re: NGK Plugs
Marlin,
I can post to you what I have sitting in my tool box at home. They were recommended to me and I changed out 2 years ago at the track. I need to stick a fresh set in so that I won't have Pete pestering me about changing my plugs. I believe that I had AC 43's in mine. Stock plug for mine was AC 45's. Spark plugs.com is a good place to get your plugs. I checked with your car and they were showing XR4's (part # 5858). I believe that mine are NGK racing plugs.
