This is especially 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 D581 would only last a few hours at 150 F but I have about 250 hours on them with 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 fo= r compatibility with the EC2/3=A0 (they are).

I do know that the pre= vious version of the truck coils (D581) are not as reliable as the D580 (Co= rvette) coils.
