My spark plug life has been the same with th= e stock 13B coils and the D585 coils.  I have had SAG with the D585 co= ils also.  As I discussed at the Paducah fly in, SAG does not appear t= o be a spark plug misfire or failure to spark.  The effect on EGT and = coolant temperatures is the opposite for SAG as opposed to no spark with ei= ther the trailing or leading plug.  I have seen evidence that SAG may = be (similar to?) preignition caused by decreased thermal conductivity betwe= en the center electrode and the tip of the ceramic.  This decreased th= ermal conductivity results from corrosion between the ceramic and the cente= r electrode and this corrosion is accelerated by the use of leaded fuel. &n= bsp;There is also some evidence for decreased thermal conductivity of the c= enter electrode copper core as the spark plugs age.

Aside fro= m the higher spark current from the D585s eroding the sparkplug electrodes = more quickly; do we have evidence that it will, in fact, improve performanc= e? Perhaps it is a cure for SAG.

BTW; my 6 D581 coils (Mounted atop my 20B) have been in u= se since my first engine start back in about 2001.  They have survived= many hours of ground test runs where cowl temps exceeded 150F (at times I= =E2=80=99m sure reached 190+ for short periods); and 200 fight hours with n= ary a single failure.

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