M156 Stage 3 Weisec Ignition Coils and Plugs?
Hi all. Just had a Stage 3 supercharger installed on my 2010 E63 and its started to miss quite bad. Compression tested 177-201 psi, best 50 bucks I ever spent, slept well that night. Has a mix and match of old and new stock plugs and coils so just gona go ahead and put in a new set of plugs, coils and primary O2
Coils, looking at the Delphi GN10232, cheap as chips and the Bosch 0986221128 at over twice the price. Anyone had any experience with the Bosch units, are they worth the extra price, comparable or better than genuine Mercedes? Curreny I've got original Mercedes coils and 3 of the cheap Delphi's replaced by previous owner, I tested the resistance and the OEM ones are like 3-4k and the Delphi 30k ohms so is it safe to assume the OEM coils are not just a rebranded Delphi GN10232?
Plugs NGK recommended LKAR8BHX, anyone had any experience with these in a boosted M156? O2 is easy, just the Bosch units.
