Im running a jdm h22a with a wet 35 shot (will be using a 50 shot soon for track)

My stock plugs are ngk g-power ZFR6FGP which are a 6 heat range. I bought some BKR7E and gapped them to .035 to try.

They seem to run fine but i think i may of noticed some hesitation at about 2800rpm. Do you think i should go back to the zfr6f plugs since ill only be running a 35 or 50 shot and my car is my daily driver. Also what gap would you guys recommend for the plugs

So basicly to sum it up: what plugs and gap should i use for a jdm h22 on a 35-50shot

Any reson why? I know that plug as ive done reseach and found out its basicly the same as the bkr7e just longer which from what some people and ngk rep... say is not good for fi/nitrous since it will even get hotter because its closer to the combustion and may break off the tip of the electroid

BKR's are not H series Plugs. ZFR's are the correct plug for a H series. They are just copper plugs. what a lot of people use on their FI motors (including me)

can you point me to a few thread that talk about the plugs. From what i read it was the opposite from what you are saying. Im curreus to know since zfr6fGP is the standard h22 plug (which i used to run) but the GP is for g-power with a platinum tip. I never heard of the plug without the GP on the end. Please let me know
