you guys have any idea what plugs I should use? for my b16 I have densos now can I stick with them?

 

with a 55 shot u should run colder plugs, go with a step colder than your stocks. and only put those in when u are going to spray that day. hey that rhymes! the best way to do it is to call ngk and tell them your setup and they will recommend u the best plugs. but rule of thum,b for minimal nitrous a step colder is safe.
