Spark plug gap

[stevedm]

Curious what gap everyone is using when they replace their plugs.
I am putting TR6's in...I believe 0.032"? ( 2.59 pulley). At What boost level does this gap decrease?

Thanks, I appreciate it.

Anywhere between .032 to .038 seems to be what is recomended. I gapped mine at .035 and it runs great. Unless you are going with an aftermarket blower and pushing more than 17 psi you will be fine. Just remember if you went with the cooper version you will need to change them out more often than a platinum plug.

I run .032 with the 2.59 on my stock blower
