spark plugs
Can anyone give me any insight on this? I had the OEM spark plugs in my '95
M3 since I first had the car and i figured I would upgrade to the bosch
platinum 4's hoping to somehow improve performance. But instead it seems
that I have lost some power since putting in the bosh plat 4. Now I seem to
have a flat spot when I hit the gas. I thought these spark plugs are
supposed to be better than the oem.
Also, is there any special programming that has to be done to the jim c chip
to accomadate these spark plugs(plat 4) so that they are used more
effeciently?
TIA
