EFI (what spark plugs are you running?)

[SCHNELE]

As the title states, what plugs are you running with your EFI and why did you choose that plug.

[David]

NGK Iridium, 8 heat range. They work go in the my kart (10 heat range though), so I figured why not.

Thanks David, do you know how the NGK heat range equates to a bosch?

[TimT]

do you know how the NGK heat range equates to a Bosch

The scales are inverse between the two brands

A hot Bosch plug would be a 10

A hot NGK plug would be a 2

[SCHNELE]

So is Dave running a really cold plug?

[David]

I think an 8 NGK is about a 4 Bosch.

I think I am running BPR7or8ES. That is from memory. It has been 4 or 5 years since I have had them out.
