May as well ask while im here. I was thinking 103's with my setup and im under the understang that you want as hot of a spark as you can get before knock occurs from that hot spark. Kinda like timing-The most you can get without kr. No KR with me. so should i just go with some new 104's? Mine need to be replaced so thats why I ask
