The socket works perfectly, but you have to be very gentle and slow when pulling it out or it will stick to the spark plug and disconnect.

Fit great when I did my spark plugs on an 07 335i.

Thin wall is perfect for the new motors

This worked well for my N55. You'll definitely want to first tape the socket to your extension, because the O-ring grips the plug tighter than most extension retaining balls will grip the socket itself. The tape is a worthwhile extra step for the low price.

Works correctly

Best socket for spark plugs even tho is not magnetic. Does have a rubber inside that will secure very good the spark plug to prevent falling. 10/10

I tried many sockets And I spend a lot of money for no reason and none of them fit Except that on I ordered from FCP Euro it was just What I want. Thank you guys

So I thought I had a thin enough spark plug socket, but it wasn’t thin enough to fit in the cylinder head, I’m glad FCP Euro had me covered, their socket worked well and had a great price. Thanks FPC Euro!

It's not the best. The 3/8 end isn't aligned therefore it wiggles around when you unbolt the plugs and the rubber fitting is so tight you can't get it off the plug once tightened. But for the price, I couldn't be happier, it does the job very well.

If I could go back, I would have definitely bought the bigger one. HOWEVER this one does the job with a proper extension and for a lot cheaper.
