Mark - I wouldn't expect just the intake plenum to cost more than the M-9424-M50BR. However, we'd need the whole kit including throttle body, CAI and a custom tune. Also, the tune should not negate any of those '200 calibrations' that are not specific to the changes included in this kit... At the end of the day you'd sell it off of the diff in dyno charts from stock to this setup. Is there any assumption on what the gains could be?
