Spark Plugs & Low Compression Engines?
I am going to be replacing my spark plugs (NGK's one heat range colder) soon and was wondering what affect the low compression build I went through would have on proper plug selection.
I am running low compression pistons 8.5:1 on my MY00. Should I run colder plugs as I did on the 10.0:1 stock build?
I haven't seen any posts or articles on low compression builds and spark plug selection. It may not even be a factor, but I thought I would ask.
If anyone has any info on this I would be happy to listen.

i would stay with one heat range colder. This will give you a pretty decent balance because you are not going to have the high combustion temperatures when off boost. Depending on how many PSI you plan on pushing you may still need to go 1 more heat range cooler.
