Aviation spark plugs have special needs. They use a non-standard 7/8" hex, and exhaust manifolds can get in the way of wrench access. A thin-wall socket is necessary for many applications. And to ensure compatibility with all makes of plugs including Champion and Tempest, a deep well is called for.

This CruzTOOLS Aviation Spark Plug Socket meets all these needs, with a combo hex and 3/8" drive for additional flexibility. Pro-quality.

Good Sparkplug Socket

  • By George from KY USA on Monday, March 17, 2025
  • Pros:
  • Review: The Socket fit the REM 40Es in my Aircraft's Continental Engine perfectly. The socket is magnetic and held the plugs in place, helping avoid dropping plugs. I didn't expect the shipment to be as quick as it was.

Not a thin wall socket

  • By Pete from 22405 on Wednesday, January 18, 2017
  • Pros: Heavy solid construction
  • Review: I have a standard Lycoming IO-360. This socket will not fit in between the cylinder head fins and the spark plug base. The socket wall is pretty thick compared to my Craftsman 1/2" drive 7/8" deep socket. The Craftsman socket fits just fine.
