Quiet air intakes

The whole point of an aftermarket intake is to get more air flow, this causes increased sound levels. I have an airraid intake and borla muffler on my 02 F150 5.4, it is slightly louder at idle, but give it gas and you can definatley hear the air being sucked into the engine. If you don't want to hear this, then it's not for you. I guess it's a love it or hate it situation.

Just installed the K&N system on my FX-4. Yes, it sounds like the old Rochester 4 Barrel kicking in when you gas it. Cruising at a normal speed, the sound isn't heard. Stomp down on it and you hear the vacuum cleaner sucking sound. I wasn't crazy about the sound, but if it helps the mileage any, it will be worth it.
