sparkplugs
This was maybe 5 -6 years ago that I read this. Maybe technology has changed? Anyone can chime in on the spark plugs if the "high performance" ones really do make a difference for Merc?
I highly doubt it would. I think nothing beats OEM
Thanks

They have 4 prongs on the bottom of them.. Car seemed to be smoother with these plugs..
