Baffle pass through solution for automotive (P-mag etc.) ignition wires.

[Flyhud]

Found some really nice high-temp silicone grommets that fit perfectly for getting ignition wires through the rear baffling. They are pliable enough that they can be can stretched over the terminal end without damage and avoid having to split the grommets. They have a 5/16 hole for the wire and fit a 3/4 hole in the baffling. Available from McMaster Carr PN: 1061T48.

This looks like a good solution to the ignition wires going through the baffle issue. Why vans didn’t include this with the kit is beyond me. How many total did you use? Right now I see 4 in the plans.

Currently guessing based off OP-40 drawing.

They sell them in packs of 10 should be enough for two airplanes and a couple of spares!
