Hi guys! I have a question I thought you guys might be able to help me with.

I have a 2018 BMW F20 1499 cc with auto transmission. I recently had some chiptuning done (HP from 136 -> 170, torque from 220 to 300, as you might have guessed from the numbers it was a stage 1 chiptune, ecu remap and some tuning on the transmission, so no mechanical changes).
Initially I was wondering if I have to “upgrade” the current OEM spark plugs to “performance” spark plugs (my gut says oem should be just fine but I thought I’d double-check.
But now I’m wondering if you guys can advise me on changes to general maintenance and intervals regarding things like fluids, additives, spark plugs, filters, brake pads, cleaning, etc.

Thanks in advance!
