Although of course with my bad memory I forgot without looking down in the cylinder.

Beyond that, the injectors were replaced like two years ago, the maf (denso) was cleaned about 6 months ago but it wouldn't hurt to do it again. Air Filter should still be good, fuel filter should be good. (Based on time)

From talking with the guys at the shop more I dumped a whole can of sea form into a half tank of gas and, after driving 10-20 miles, will do a couple of "Ferrari tune ups". Also going to do the seaform through the intake, gotta find the spray version. Lot of stuff is still out of stock a lot in my town.

I usually drive her like a grandma and I guess never hitting high rpm's would cause the build up?
