FWIW, I rerouted/repurposed the aft end of the former regulator cooling hose to blow air onto the ignition module stack. I figured that a bit more air on the two modules would help keep them a bit cooler -- after 1,000+ hours, so far so good.
ps -- Per Van's recommendation at the time, I relocated my "Ducati" R/R to the underside of the avionics tray. This has worked out fine so far.
