One step colder plugs and E85

[Spamby]

Time for a tune up. Want to change plugs but am getting conflicting info for the plugs with an E85 tune.
Basically, should I go one step colder or keep them at stock heat range?

Great question.

Unfortunately I have no idea.

Obviously there are many other factors that could play in like compression, timing, ignition system etc etc.

for stock or close to stock compression you want to stay stock heat range. Its like putting on two condoms otherwise. Only go cooler heat range for pump gas and generally if you are experiencing knock or in higher compression and/or boost applications.

And that's kinda what my old school thought was.
No knock here and stock compression so I guess that's that since I'm on E.
