I have a '95 (#386) w/25k mi & what appears to be original plugs (AC 907s) which looks to be the same as 41-907 in owner's manual. Manual says gap .050" & plug I took out (#3) was just that. Car runs good & smooth, but from what I gather, plugs s/b changed. Maybe it will run even better. Easy & cheap enough.

I see reference to 41-602s. Is that same as 907? Car is not raced, just plain old spirited street driving. My inclination is to go with copper ACs, but i saw 1 reference that Haibeck recommends NGK TR5IX.

Thoughts welcome.

Thx
