Click to expand...

as far as the plugs, i think most of us here would suggest or agree on autolite 103's
 
Yes, just tell them Autolite 103's.

If you have to get the couplers local your gonna have to find a performance shop that deals with turbo's.
 
go to the parts counter and ask for a set of 103's...


and yes autozone does sell the coupler, it has a "spacer" making it fit different things. but, on my set up it got hot and failed
