Spark plug OEM BMW or BERU
Ive ran Beru ultra copper core for a couple months now and they are one step colder. I honestly dont even check gap on them and my shit runs smooth.
Pros: runs smooth
I use only NGK or Beru spark plugs.
use BMW OEM plugs from the dealer. Yes the are expensive but I have never had a problem with misfires and I've put over 100,000 miles on my current E36 and over 150,000 on my first. While they are suppose to work and be interchangeable according to the manufacturer the NKG you buy aftermarket are supposedly different than what you get from BMW
Pros: no misfires, high mileage reliability
Cons: expensive
Vehicle:
BMW
Mileage: 160934 km
use beru plugs rather than Bosch, a lot of Bosch plugs sold for this application has the wrong heat range which can cause misfires.
Pros: correct heat range
Cons: wrong heat range
I had similar problems with mine until I tried stock F80 M3 plugs. Mfg #12120039634KT1. Mine was 07 N54 FBO.

Guy was gunna charge me $720 USD for changing my serp belt and another $550 USD for changing just my spark plugs. That's $20 for the serpantine/drive belt, $150 for the belt tensioner and I think another like $120ish for spark plugs (B58 engine). So in total I saved myself roughly $1,000 just doing it myself.
Pros: saved roughly $1,000
Vehicle:
BMW
Had these Beru plugs put in last year. Are they the kind that’s at greater risk for damaging the engine?
Cons: risk for damaging engine
Part number: 06K905601M
I ran Beru RS7 plus which are one step colder when I tuned stage 1 and they didn't last at all. Might have been under 10,000 miles. Recently went with NGK plus that APR reccomends for stage 2 and so far so good. No misfires since.
Pros: no misfires
Cons: didn't last
Mileage: 10000 km
I swapped out the oem plugs for Beru rs7 plugs when I went APR stage 2 at ~3k miles. The car ran well. Fast forward to the present with over 18k miles and is20 swap, and I noticed a few stumbles at idle. Nothing major but I figured I'd change them since APR recommends 10-15k mile intervals (visually the Beru plugs looked fine).
Pros: car ran well
Cons: stumbles at idle
Mileage: 18000 km
