NGK CR8EG spark plug case

! ! ! Attention ! ! ! The V4 of this model had incorrect clearing distances on the thread and thus the cap could not be screwed fully to the case. This is now fixed in V5. ! ! !END of Attention ! ! ! This was designed to hold my spare NGK CR8EG spark plug in a safe, waterproof place. Away from all the dirt and moisture while on a trail. It is designed specifically for this type of spark plug. The tip of the electrode is not touching the bottom of the case to maintain the correct spark plug gap. The sparkplug is sitting on its hexagon "nut" not on the bottom tip. M30x3,5 RH thread + rubber gasket ensures waterproof sealing. It might fit other spark plugs, some of the dimensions are in the pictures. Upon request i MIGHT be able (due to time constraints) to design a case for your specific spark plug.
