Another NGK TR-55 Spark Plug Gap Question
#1
![Exclamation](https://ls1tech.com/forums/images/icons/icon4.gif)
I have NGK TR-55 V-Power Spark plugs for my 02 WS6 and I'm going to put them in with Full exhaust and a lid. Well I looked at many threads but I have just got mixed gaps. I have read that some people say the best is .55. Some people say .5 is the best. Some people also say .45 is to low but some still like it. Well how would either one make a difference? Which one would be better for me?

Split the difference and go .055"...it'll work great!

TR5 and TR55 are the same plug, just gapped different. The TR% comes gapped at .040" and the TR55 comes at .060". Same heat range and all!
