Electronic ignition

[jclark]

I have been running the Jeff Rose (ElectroAir) system for over 1600 hours on and O-320.
Started with REM37BY's on the one mag and on the EI (gapped around .035).

I asked Jeff about automotive plugs (around 2002) and suggested the 386's with the expectation of some performance loss. I tried them and I fact could tell a slight difference. They otherwise performed just fine. I think I gapped these at around .035 as well.

Went back to the REM37BY's for a thousand hours or so.

Recently have been trying the NGK BR8EIX's (Iridium). They seem to work fine. I have used them for a few hundred hours. I did NOT change the gap on these.

I have two P-Mags, 114 models, that use NGK8BR-EIX or ES Plugs with thread size adapters. The EIX is iridium and cost $7.08 online, the ES plug is in the $2-3 range. I installed the EIS plugs. Emagair recommends using either one, no preference, just replace every 100-125 hours. I have 150 hours on my set and seem to be doing fine igniting premium mogas. Dan

One consideration should be how the different manufacturers deal with connecting the wire to the plug. On the LASAR they use a standard two nut system where you hold the wire stationary with one nut while twisting the other onto the threads. If this is the case with your electronic ignition then aviation plugs would work fine, or auto plugs, depending on your preferences.

The one place where I tried aviaiton plugs and was not happy was with the Emags. The issue isn't the plugs it's that EMag uses a single nut to connect the wire to the plug and the nut has to slide/rotate on the wire exterior if it isn't going to wind the wire up while turning onto the plug threads. Even lubing it with silicone grease and pre-winding it the other way doesn't prevent localized twisting that, in my case, was enough to shear the inside insulation. This resulted in arcing internally and the plug didn't fire.

I have since switched to the EMag auto plug harness and couldn't be happier.

Just my experience FWIW...
