Thanks Tiger
part of my problem was my car (w140 1993 300SE) wasnt original plugs,
local MB dealer (list) uses Bosch F8 !! copper electrode, so it sucks
i ask for Bosch platinum even for im****t, they cant do it for me.
thats why i choose on Champion from a good friend that owns a MB.
i have read about Itrium but not about iridium spark plugs on street
cars.
now i note a difference, works better, but i still think im not using
"the best" sparkplug
when your local dealer have wrong info youre lost!!!
best regards
