Is there anybody who try to use these spark plugs - R6601-8 (3033)? I try to use a 4554 (R5671A-8) but I am having problem with my ECU etc... becouse 4554 are non-resistor. 3033 are a little expensive, but they non-projected and resistor type and it is heat range 8

Hi you can try them the most important is the correct heat range for your set up and gap what ignition set up do you use to have problem with 4554? i used them on NA ans turbo Honda without issue

Probably an MSD.. We sell more 4554s than any other plug.

it feels like a missfire still, it cuts ECU from power or something like that

under heavy boost pressure it is normal with orjinal gap adjustment, you should gap down those spark plugs until engine revs normal without having misfire.

I try to gap the spark plug as much as I can... there were maybe .020, maybe less and still the same. With BKR7E it was OK with gap about .030. I said it feels like a missfire, but I can feel that the ECU cuts it

does it cut hardly or just like misfire and revs to the end?

what is your setup can you give some information? did you change a new set of NGK Spark Plugs? what is your boost pressure? it could be your fuel pump.

if you are having the problem with non resistor type like your 8's plugs try this one R5671A-8 instead of r6601-8 or try BKR8EIX iridium.

Did you try without the MSD box? just keep the blaster coil

he has no problem with different type of spark plugs. I think it is not from the ignition box.
