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.

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

Works as you would expect, not clear it is any better than a Craftsman thin wall deep socket. The Champion socket works better at retaining the plug.

As others have stated this socket has thick walls. I choose it because I needed the shortest overall socket length possible due to restricted space (engine baffling). It did hit the cylinder head cooling fins before bottoming out. I assumed I would have to lathe down the O.D., which I did. After reducing the O.D. it works fine.

It works fine when used with Champion spark plugs. But, it isn't as thin-walled as the Champion plug socket - and therefore every once in awhile it won't quite fit when removing or installing Tempest spark plugs. This happened on Continental TSIO-360 and GTSIO-520 engines, where on two or three plugs the socket was simply too fat to fit past fuel injection hardware or, in some cases - past the spark plug relief cut. A little judicious grinding solved the problem, but now the pretty chrome finish is toast.

This was initially was described on their website as 1.5 diameter. After bringing this problem to Aircraftspruces attention they changed the diameter to 1.25 (And said that customers simply have to see if the socket fits their requirements??!!) In order for an extended socket to fit into the sparkplug well of some Lycoming 0-360 engines the diameter has to be 1.18 (1 11/64) or less. This socket will not work unless it is modified to that diameter. Buyer beware !!!
