Slick mags and plugs for sale

One slick 4370 and one 4372 with harness for 4 cylinder lycoming. Also 8 Champion REB37E spark plugs. These items are removed from a new lycoming IO-390-EXP119 engine. The plugs were run for 2 hours in the test cell. I don’t believe the mags were ever run and were installed after the test cell run because the harness looks like it has never been opened.
