If you have 8.1s there is a very distinct intake whistle that occurs as you come up on plane it's caused by the air flow through the throttle body and can be remedied by installing a thin plate between the throttle body and intake manifold. This plate has a small finger that protrudes into the air stream and slightly changes the air flow which cancels out the whistle. They are available through any crusader dealer.
