Can anyone give me a good plug recommendation for a smallblovk 340 with w2 econo heads, e85 fed FITECH fuel injection and about 8PSI of boost to start? Did some research and came across a few different ones but there always seemed to be one thing off from what I wanted when searching through part numbers (non-resister type, not recessed, etc...). Thanks!

ngk-8 race plugs, part number r5671a-8 stock # 4554

10.secdarr, I came across that plug a few times doing some web browsing but what concerned me is 1) it is a non resister plug and 2) it doesn't have a recessed tip. Think this will work with a fitech EFI system and boost? I don't have much experience with spec'ing out plugs for boosted EFI applications but I have always heard non resistor was a no no for EFI and it's better to use a recessed tip for boost.

And fwiw I'm running an MSD box with the FITECH and am using a new set of MSd 8.5 super conductor wires. They supposedly have good EMI suppression so hoping maybe that'll fix the issue of having a non resistor plug?

Does the Fitech system need resistor plugs and low resistance low EMF and RMI plug wires ?
If not one of them as a resistor components should work, correct?

-8 is a little hot unless it's low boost. I would start with -9
