Just A103, but I need to pull them out and try cutting back on the back-strap so it's more like the AR. Unfortunately my bandsaw needs a new blade. I guess I could do it in a vise with a hacksaw. You might even be able to snip it with a pair of diagonal cut pliers if you have a good pair.

Anyway, I tried other octanes as well- 2 tanks each, and didn't find cost effectiveness for myself. Everyone should do experiments for themselves when it comes to octane/plug combos. Too many variables. I do like the standard plugs because those help with diagnosis- build up deposits. I just don't put them in the wife's van. It's not so easy to change Windstar plugs- the cowl has to be removed, and it helps to take the nut off the dipstick bracket as well. There are cases where long life plugs make sense.
