I was wondering if anyone noticed an increase with just a K&N filter. I'm looking for a little more power, but would love the "whoosh" noise from an intake more. Anything like that with a K&N? Are there any baffles that can be removed to let a little more air in? Not sure I'm ready to drop $300 on the Carbonio. Where's the cheapest place to get the Neuspeed P-flo, and is the anywhere else to get the Carbonio besdies the APR site?
