Santa is gonna be bringing me a Cobra Intake for Christmas, so i think upgrading to a larger mass air will be a good idea....i am wondering what the best one is...my setup will eventually include a 75 shot of zex...should i get the C&L, or the Pro-M...could i keep the fenderwell part of my MAC CAI with the C&L, and should i get calibrated for 19 or 24 pounders, which will be better with the 75 dry shot? oh and 65 or 70 mm throttle body?
