The upper spark plugs on the #1&2 cylinder are really really close to the cowling. I currently have high altitude sparkplug wires connected to champion RHM38E plugs. The wire insulators have a 3/4" diameter nut, which limits the type of plug I can install. I understand there are shorter plugs available in the 5'8" diameter. My question is are there shorter 3/4" diameter plugs out there or can I somehow reconfigure the wires to fit a 5/8" plug?

Thanks for the help!

Try Tempest, was Unison, they are shorter.

Or bite the bullet, phone Brad Dement and get a P-Mag and stick auto plugs up top
