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.

Providing there's no cracking on it, and the metal contact and spark areas are in good condition, then there's no reason to not reuse it.

Not an issue. Washers aren't supposed to get crushed!

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.

Yes, these are the 2 step colder plugs. They were acquired from aa legit source.
My cause for ignition problems was a micro fracture leak on my VC.

the non crush copper washer means the plug is indexed to the injector and suppose to face a certain way for that application
