Can I reuse this Brand new Spark Plug?
Long story short My cyl 1 coil has went for the second time, first time being when I accidently got a little fuel on it from my injector job & now this time it looks to be contaminated with some oil. Redoing my VCG & VC but was wondering if I can reuse this plug I've cleaned it and no signs of arcing.
One other weird thing I noticed was that the copper washer does not look to be compressed at all even though it was hand tightened and torqued to spec, does everyone else's look like this? Thanks. PICS down here View post on imgur.com |

I have never seen a spark plug with a copper washer like that. And in the States, NGK does not make one like that for the 335i.
I wonder if that is a counterfeit plug, especially if it was giving you ignition related problems. Do the other 5 plugs look the same? I would get new ones from a reliable source. |

My cause for ignition problems was a micro fracture leak on my VC. https://burgertuning.com/products/ng...der-spark-plug |
