I put a K&N on the the stock box and noticed a small improvement in mpg, but nothing to rave about. The performance gains of an after market intake sounds great for a 'small' investment, but what about mileage improvements?

Sorry missed your post....

When I first installed the SC w/stock airbox K&N filter, it was sucking down gas and after I put the intake in it was like it could breathe again and was back to normal. The difference is night and day, I'm so amazed(not really) Alpine dropped the ball on this....I think it should be the standard to add a intake kit with a SC.
