Asid= e from the higher spark current from the D585s eroding the sparkplug electr= odes more quickly; do we have evidence that it will, in fact, improve perfo= rmance? Perhaps it is a cure for SAG.

Perhaps it helps that they get plenty of air flow (during fligh= t) being pretty much in blast from the rad exit.  I generally run the = rad aux fan for awhile after shutdown; but I=E2=80=99d guess high temp is l= ess of an issue when they are not operating.

I highly recommend t= he air cooled enclosure as Steve Boese (and I) use.  This is especiall= y important on the D581 and the stock RX-8 Renesis coils.  The Renesis= coils have a fairly high failure rate even on the car.   The D58= 1 would only last a few hours at 150 F but I have about 250 hours on them w= ith the airbox at 120F.

Don't forget to do the coil disable test to = check for failed coils prior to every flight.

I have a set of the D585 coils but have only evaluated= them on the bench for compatibility with the EC2/3  (they are).
