Aviation spark plugs are too expensive and too fragile to handle carelessly or leave laying on a work surface.  This durable rack will hold all the spark plugs from a 4 or 6 cylinder engine.  

*The plugs are held at an angle for easy access

*Includes a slot by each plug for the gasket

*All rack positions are labelled 1-6 and top/bottom so you know which engine position each plug came from

*Wide base helps prevent tipping

*Convenient carry handle for transporting

Please note that a couple of our customers found that certain plugs did not not fit.  We immediately changed the design, took care of those customers, and now this redesigned rack should work with all aviation spark plugs.
