I plan on running 8psi daily and maybe 10 at the track.
from what i understand I need to run a colder spark plug i think the stock ngk plugs are BCPR6ES-11 how much colder should i go to one degree or two. also what kind of pipes should i use for the charge pipes will radiator hose work and one last question where can i find silicon coupling for cheap every where i looked they were very expensive and I'm on a budget.

I would appreciat any help

2 deg. colder,zex plugs are good and not expensive, $30 set. ebay silicone hoses $10- $20

 

any good part store, not pepboys/autozone should know exactly what you mean when you ask for 2 step cooler plugs, customcoach has intercooler piping, mandrel bends. Look around site. General discussion has his site somewhere on first page. Egay if your in no rush.

 

BCPR6ES-11 is stock
bcpr8es-11 is 2 steps colder
pep boys stared at me when i asked them for colder plugs...i had to give them the part number.
