I've used the 3 electrode WR7DTC for years....
Looking for something super hot to light off the rich E85 mixture I'm running, already have 034 HO coil and 034 EFI on a 2.6L 20v.
Was thinking about running the "BOSCH PLATIN F5DPOR R1" they lok pretty "futuramic"!

Yeah, don't run anything expensive. They will get glazed over and have to be replaced just as soon. Close the gap and crank up the dwell on boost

Running these right now...
Left to right cyl. 1 thru 5, about 5000 miles on them, alot of them are track days
1 looks like it's burning some oil... 2 maybe a tiny bit, 3, 4 & 5 look good.

I have been running Denso IK22s Iridiums on the AEB (1.1bar) and the AAN (1.35bar). Both on E85. Runs smooth. Gapped to 0.7mm
