Spark plugs for turbo,s

[Anonymous]

Any thoughts on turbo specific spark plugs or is a good set of standard plugs the go

good plugs, 1 heat range colder than stock, maby even a narrower gap.

If you can find them, and they are out there, I'm using the AR-33's racing plug (autolite). Don't know how many steps colder, but they are more than one or two I know of. I have my gap set at @ 0.027", too big a gap and you will blow the spark out with a turbo engine. This is with 10 psi of boost. Hope that helps.

We've used the AR-33s and they work fine. Right now we're using the NGK equivilant, but I don't recall the PN off hand.
We've got our's gapped at .025".
When the aluminum head comes out then you'll need the Autolite AR3934s.

Later,
