hey everyone. im looking for 1 step colder plugs for my 91 accord. yes i will be going boost, so im just gathering parts. stock is: ZFR5F-11
i'll be boosting around 6psi with SMC and 450cc DSM. i know others are using bkr7e, but do i need 2 steps colder??? oh and what gap should i use??? stock is .044. a lot of people use .030 - .038, but im not sure since i drive an accord. thanks!!!

 

A lot of people actually use .025-.030. Anyway, 1 step colder is find for 6 psi. Once you hit about 10 psi or more I'd say go with a 2 step colder.
