With this increase in efficiency (much less restriction), the n/a’s get an easier working motor which means more power and more mpg at any given rpm level.
I got my figures from TVT (take that with a grain of salt, lol).
They had compared a factory Crossfire N/A airbox with paper filters, to a gutted C320 airbox (all baffling removed) and a pair of K&N filters.
Between the bigger volume, TVT intake tubes, and freer-flowing filters, the car is MUCH more responsive.
Still, I've always flirted with the idea of a NW dual. Saving my pennies for wheels now though.
