This socket was perfect for removing/installing spark plugs. The only issue I had with my extension was that it does not properly fasten to the socket, so it would be left inside stuck on the plug. I did not try using a different extension to see if that was my issue, so I'll try that out next time.

High quality product !

Must have for the N55 found in many BMW's. You will not get a regular socket in the plug hole without damaging the engine, buy it and be done with it.

I purchased this for my E90 335i and it worked exactly as desired. The walls did not get stuck in the channels and created a secure connection with the plugs. As a tip for anyone that hasn't had the issue before, use an extension with the socket and then apply a thin layer of electrical tape around the 2 so when you tighten the spark plug, you can break the seal and not have the socket remain on the spark plug.

Socket was exactly what I needed works perfect

Quality tool. Simply works!

Lets put this simply, you need a thin walled 14MM spark plug socket to change the spark plugs, plain and simple. This one works great, gets the job done.

Fit as described but gets stuck with the rubber. Upgraded to magnetized one

Make sure have a pair long nose pliers while use this socket. Yes, It will get stuck with the spark plugs. for the prices and I always have a long nose pliers sitting around, It is good let the pliers have some workout that sit there and get rust LOL

Made life a lot easier , works the way it should
