Spark Plug (PIC)
What this look like to you guys??
I'm E85 running about .78-.81 lambda at WOT. 1.07 @ Cruise
3.0 Pulley with Intake, and full exhaust(catless).
These had about 5k miles on them.
These normal on E85 or what? I'm unsure what they should look like, my last set-up was regular 93oct and it was running rich as hell, plugs were just pure black with soot.
Thanks in advance,

Thats really rich, you can adjust your lambda to .82 - .85 and it will run a lot better on e85. Your plugs should have a tan / brown color to them, it it looks white at all your running too lean. It they are black like that your running rich, and from the look of those way too rich. The 2 on the right look like they have lots of carbon build up on them.

u dont need colder imho with your mods, i would run OEM NGK plugs the center electrode porcelain should be chocolate brown to beige. They should last 60 k miles easily. And torque your plugs down to spec, loosen 3/4 turn and re torque to spec. The crush washers dont look crushed much. my .02c
