The long socket extension for replacing spark plugs worked great. It's got a high quality chrome finish, a magnetic end to keep the plug in place while you lower it into the cylinder, and a knurled section on the outside finish to give you some grip to hand tighten before final torque is applied through the 3/8" socket end. Not a cheap took but worth the price once you use it.

Excellent, Genuine, Perfect fit!!!

I used this to replace spark plug on my 2005 Z4 with M54 engine. The magnet inside holds the plug so you can hand screw it on the head before tightening with a ratchet/torque wrench. The overall shape of the tool is perfectly adapted and makes the job so easy.

Worked Perfect for my BMW V8 and other top angled V Import engines that split the valve covers.

very nice tool dose not fit the 2 rear cylinders on a E46
