Spark Plug Advice - \'15 435xi MT - Stage 1 Tune

Yeah, that question again....

I took over on this car 12k miles ago (now at 74k). AFAIK this car had no drivetrain mods, except for a Dinantronics boost controller. I got rid of that in favor of an MHD tune and have been running that as a daily commuter (rural miles) for about 6k miles. I'm starting to stumble a bit at idle and the other day was discouraged at WOT. I haven't pulled plugs to look but my right foot and right hand both suggest I'm due.

Should I just be sticking with the Bosch spec or OEM part number for bone stock? I don't mind changing them more often if someone has some better experience/insight for where I'm at, currently. If there's any additional mod in my future, it would be a high flow catted downpipe.

Thank you all,

-z

You should be good to go after a fresh set of OEM spark plugs.

Thanks. I tried my best to overthink this. I'm glad this was your guidance and not something else.

OEM is where I'll go.
