Spark Plugs
Howdy fellow Festers! Question for those of you that are running a full ecu tune or BMS with more boost.
Are you guys running colder plug ranges with the higher boost levels over stock? Just curious since I have seen zero posts about changing plugs other than for normal maintenance. Thanks for the replies! ?

I just re-gapped to 0.022" and I haven't seen any misfires yet at 27psi and all sorts of fuel combinations

From experience on other forced induction motors I have always changed to colder plug ranges when increasing the boost. I'm wondering if the increased boost and heat are wearing out the plugs more quickly.

Completely different engine, but nevertheless...in the Lightning/Harley world we're running NGK copper plugs with varying gaps and changing them every 10k or so once we're past like 10psi. They give great readings and don't hold heat like titanium or iridium. I'm sure BMW knew what they were doing when they picked the plugs they're using, but now what we're pushing well beyond that, factory spec plugs might be out the door.
