S4 intake swap on to S3 SE..pro's and cons?
Hey, lookin for upgrade choices soon. I know I'm dropping a S5 N/A in my SE. I've researched and found my S3 intake is really constricting and most would upgrade to S4 intake. I've heard though that there is cold engine drivability problems with this swap though. True or false?
Second, MPG...does it go up or down with this swap?
Third, all the vaccuum hoses, solenoids, etc, will they swap right over to the S4 intake or what?????
Searched a bit and came out with little info. So MANY threads!!!

one thing to keep in mind, the S4 motors have an extra set of injectors, which was a pretty good improvement over the S3... i would think if the manifold is a better flowing manifold itd probly increase gas mileage, due to less restriction, but i'm not real sure...
