I used CPU heat sink paste, used a finger to coat thin film over entire surface, torqued down in three steps, cleaned excess at margins with a q tip. Idea is to transfer heat from heatsink surface on underside of ignition module to plenum. Covering entire heatsink surface is the goal; can put on too little with result of incomplete transfer of heat resulting in hotspots with potential to burn out IGM, but too much only squeezes out excess when torqued. I play around a lot with electronics and ham radio. KC4NWF
