The RV-series aircraft engine baffles have a hole to allow access to the rear cylinder spark plugs. This plug will fill that hole and can be inserted from either side of the baffle. Mine were inserted from the outside because of interference with the baffle seal on the inside There is a slight ridge that should prevent the plug from being pushed out if inserted from outside. Mine were printed using a TPU/flex filament but they should probably work with a rigid filament too.
