AR52's need to be smaller?

Post  powerstrokeace on April 7th 2012, 5:12 pm

Guys I've been finishing up the current motor and put in exhaust studs and now I can't get a spark plug socket on to tighten it up. Is there and thing that has the smaller 5/8 hex plug? Current spark plug is an AR52 autolite

AR3934 may be a place to start.

Ok after some searching I have found out the 52's are a few steps hotter plug than the 3934. And I happen to come across the NGK r5671a-8 as the equivalent plug at the local motor cyles shop for $1.55. So I pick them up and will try these in the new motor Lem.

Looks like cold weather and rain this Sunday so no testing for me.
