for my immaculate 940 GLE sedan ...
I changed the plugs last night.
I last had put on BPR6ES NGKs and now put BPR6EY.
OK the old ones were regaular, these were v-groove... they had nothing else in stock.
Is the "Y" for the v-groove and hence all is well, or is there some other difference and I installed non-recommended plugs?
On that note, it drives great. I also did a TB cleanup, man it was sludgey.... the accelaration and idle is much more smooth now. All went well, I removed the TP switch to not get cleaner in it.
