Product Information

A 14" long 16mm socket used to reach spark plugs easily deep inside most BMW cylinder heads

Replacing spark plugs should be part of your BMW's regular service intervals. With that said spark plugs are located deep down inside the cylinder head and require special sockets for removal. Most spark plug sockets are standard length, except for this one.

Using extensions on spark plug sockets is not ideal and can cause issues in terms of removal and reinstallation. This one piece unit from CTA measures in at 14" and features a 5/8" or 16mm 6 point spark plug socket.


  • Extra long spark plug for hard-to-reach plugs
  • Features internal magnet to hold spark plug
  • Knurled end
  • 3/8" square drive
  • Chrome plate finish
