Overview

Aviation spark plugs have special needs; using 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. To ensure compatibility with all makes of plugs including Champion and Tempest, a deep well is called for.

Five stars for now, because I cant just offer a comment without a rating: the one I received on 7/3/2023 appears different from what was shipped in the past, and different from the photo. The one I received is satin-finished, 1-1/8 outside diameter (so thinner-walled than some purchasers described) and it does include a magnet inside the well, which reduces the inside depth to barely 2-3/8. Havent tried using it yet to determine if that affects its fit on Tempest or Champion plugs. Five stars for now, because I cant just offer a comment without a rating.

Perfect fit for removing spark plugs. Total contact with the base and thin walled to clear the chamber walls.
