SP-1 with dominator adapter. Can be used with 4150 with the included plate/gaskets. I have used these intakes before, and they work well. Fully ported in the plenum and port matched. Work is decent, not perfect, but won't cause you any problems. $250+ shipping All forms of payment accepted, but postal MO, check perferred, so we can stay away from the bank charges. Add a few bucks and use your CC or paypal.. no worries, eveyone is happy.. JW
