People love to jaw about filtration and often rag on K&N for supposedly letting in too much stuff but my throttle body and fuel injection housing are as clean as the day I got the car 40k miles ago.

So do you think an AFE Stage 2 dry intake would improve gas mileage? I know when I went to a stock box from a SRI on my GTI, I lost 2-5 mpg.
