Lets talk Spark Plugs...

Ok when switching to E85 to yall recommend the same Spark plug as gasoline, hotter or colder? Also what would you/do you gap them too?

Well, there's this so far:

I think the general wisdom is at least one heat range colder and probably two if you're using a power adder.

This is a quote from this post. Not sure if it helps you or not though haha.

You will need the injectors now.


OK, but you already have the injectors from round 1.


Go with the NGK BR7EF plugs gapped right out of the box for both setups.


I had the Billetflow idlers and switched for the Metco Double Bearing Idlers. I like the Metco's better.

Ok I am running NGK R5724-9 Which are badass plugs and my buddy is running BR7EF and we were trying to decide which were best for E85.

I run br7ef in my truck and I will be running them in my cobra.

BR7EF, they've been great thus far!

These are the ones I just pulled out. This is why Josh was asking about what spark plug to use. They have maybe 3,000 miles on them using E85.

My plugs look brand new when I pull them out. :shrug:

Looks like you got water down in the spark plug holes. The one plug especially looks corroded.

Yeah one plug looks bad
