Spark Plugs

Hey everybody ,
I wonder if this plugs (bosch super 4):

will fit my 1994 BMW 520 with M50 engine (6 cyl).

It has 4 contacts. Do you guys know if it is of any use having 2 or 4 contacts instead of 1? Or is just hype?

Thanks.

the M50 engine always has spark plugs with at least 2 gnd electrodes.

i'd use NGK BKR6EK, this spark plug is the same that BMW recommends and sells for the M50.

don't waste your $$$ on platinums or other "super" plugs.
Go with stock plugs from ngk

or bosch

what if this super 4 and normal NGK cost the same? which would you suggest I buy?

stock NGK or Bosch

it's not about the $$$, it's the performance

What about those denso iridums?

So you say NGK performs better than Bosch super 4? "Super 4" sounds a lot better than "stock NGK"


What is your opinion guys, which will perform better? They cost the same (or nearly the same).

NGK's...
