First I see specifically made to match the M plug, and not dangerously stick down from the metal protective shield. The only reason I want the experts' approval is to make sure the thread's diameter is correct, and not too loose, which could lead to stripped threads. I also noticed it's a lot longer than stock, but that shouldn't be an issue IMO. It's time for another oil change due to time, so found this just in time
. Thanks gang.
