hi, i plan on going turbo on my b16a3(delsol engine) and was wondering what kind of plugs i should go with? what are the guidelines when choosing sparkplugs? i've been told 1-2 ranges colder, gapping etc. but what do they all mean? what should i take into consideration before choosing? thanx

 

NGK bkr7e, gap at .30-.32

 

Ditto, this is one step colder and slightly smaller gap.

This will be fine for you application.
