I got 3 and the other was wrong.

One of the plugs was an autolite and it wasn't even the right size. Kinda sucky. How do I send back? Real busy right now.

Works just like it should
Bought this for a 2011 BMW 550i xdrive. This fits perfectly if not just a bit too snug. It took just a bit to get it off the oil filter cap. Saved the day though!
