So I'm on the Hunt for colder PLUGS
 

I've googled the NGK zfr 5&4 f's and I cant get a match for my Prelude motor. The ZFR6F's clean the plug too much under boost to where I cant tell if it's a go or no go on idnition advance. DMC1 also see this when he was over trying to help me get her going before the Ching Chong blew a seal. Where do you guys go to get colder plugs for PRELUDE's H22A's or if you know where to go post up.
