Boys and Girls,
It is still -12C but I feel spring is around the corner and bought my Valvoline VR1 and Fram Gold filter as usual, but I have never changed my plugs....I know these littles wars start like this but WHAT IS THE CONSENSUS ON PLUGS FOR .92 S4 No Politics only Tech Talk>:)

It's tough to go wrong with NGK. For a '92 BPR7ES are the standard plugs, BPR7EIX are iridium tip. You probably won't notice a difference in performance between the two.

Those are both projected tip. If you have oversized valves you want non-projected (BR7ES or BR7EIX) so as to avoid the valves potentially hitting the electrode.

There's some debate about the relative merits of the projected vs. non-projected tips. I think I've got BR7EIX non-projected in there and they're working fine for me.

Do a search, you'll find lots of opinions and info.
