I want to run a colder plug than the bkr7e's I have now. This means going to a resistorless plug like r5671a-8. Both are Ngk. Will this have any negative effect on my COP setup ?

i know this may be old news but i ran ngk racing in a 7 heat in my 01 engine running 01 wasted cops and it messed with my cam sync to the ms3x. put in just ordinary ngkr's in a 7 and all was better. i have since switched to lsx coils but still run the r's.

i need 8's, there is no such thing as a bkr8e, i have to go to a resistorless racing plug for a 8

switched to resistorless a little while ago to try to get better spark out of my batch fired COPs...didn't work but still have the plugs in and they do what they're supposed to.

Those are iridium correct? I want to stay with a standard plug. The part number I posted it a standard v- power racing plug. Just resistor less. If they have no negative affect because of the added electrical noise then I will run them. The only thing I have read is that they mess with your radio, but I don't have one so that won't affect me. I just wanted to know if anyone has experience with resistor less plugs

I use resistorless plugs in the XP car.

I've noticed the Link ECU keypad sometimes goes haywire after a run. I think I'll try putting some capacitors in the power system for the ECU. No dyno proof but the car felt better at the high boost. I haven't had a misfire or the ECU go 100% nuts, just the keypad displaying junk. Power cycle it and everything is ok.

Denso has a resistor plug of the proper size, in a heat range comparable to the NGK 8, that is not precious metal. K24PR-U11

im still not convinced we need any colder than 7.

Next time I buy plugs im going back to stock 1.6L ones. Just considering they went 1 step hotter with the 1.8L.

I run resistorless plugs without any issues. Frankly I think it will run exactly the same with "normal" 7 heat range plugs. LS coils >>>>>> any magic spark plug

These are my current plugs - same as Flying Miata sells
