[QUOTE=BowTie Rick]You used it on a supercharged application, that is the difference. You created more pressure drop to pull air through it. On a naturally aspirated, I still say exposed will do better. QUOTE]
I run a K&N on my DMax now so I can't knock them too bad....
The gain we saw on the S/C, I think had more to do with the fact that the Whipple intake pulled cooler air from outside the engine bay at higher RPM's and the K&N set-up had a tendency to pull the warmer air from the engine bay. IAT were lower with the Whipple set-up.
Bottom line I'll sell the whole set-up for $100...even help him put it on if he's local.....can you beat that Rick :yuk:
Oh yeah ......nevermind
