Which plugs for stock 4v??

[5.0calypso93lx]

I've never owned a mod motor before, let alone a 4v. What plugs should I put in this thing? Car is bone stock and has 88k so I'd like to do a few maint. items. thanks :bigthumb

I have had good luck with Autolite 764's and NGK TR55's in my 2V. I don't see any reason they wouldn't work just as well in a 4V.

I put stock motorcraft plugs in mine but that was cause I got a discount and they have been in there for like a year and a half no problems.

just use your stock replacement plugs. Use a good set of platnum's.

I prefer ngk tr55's change em every 25-30k for hard driving.

I ended up putting the TR55IX's in. It had Autolite 764's in it before. Thanks for all the help! Probably the easiest spark plug job I've ever done.
