Review on πŸ”§ Assenmacher SP1412 Thin Walled Spark Plug Socket: 14mm, 12-Point Speciality Tool by Warrick Infinite

Revainrating 2 out of 5

Use a JTC spark plug instead.

While the product looks and feels high quality, I don't like that when changing spark plugs and trying to remove the tool from the built in spark plug, most of the time the Socket remains attached to the spark plug and instead disconnect the socket extension from the spark plug socket. In order to finally loosen the spark plug connector from the spark plug, many attempts are required, this is done carefully and with the right force. I suspect this is because the bushing has a gasket on the underside of the bushing that slides over the spark plug bushing and applies pressure to hold the spark plug in place. This outlet will not make you the most efficient person if you make a living like me. I have had the best experiences with a JTC socket that a colleague of mine owns. It has pins on the bottom of the socket, no gasket.

Pros
  • Comparable to BMW #121220
Cons
  • Upgradeable
