Odd Noise from Front

Ever sinced I installed that K&N Typhoon system, everytime I shift to 1st, 2nd, or 3rd, sounds like the heatshield for the intake rattles up against the high pressure line on refrigerant.

Anyone else experience that or have a fix?

My thinking of a technician is that the motor shifts to the rear with OEM motor mounts and rubs against it, but I could be wrong.

Mine does that too. Unfortunately, I haven't bothered to look into it yet.

It'd be cool to find a fix. It robs the coolness factor when you punch your foot to the floor and it sounds like the hamster fell off the wheel.

Finally stopped raining, checked on it...The only solution I can see is by either applying urethane motor mounts (to keep the motor from swaying back and forth on the gas pedal) or to add a piece of foam against where it makes contact...way to think K&N on that part :P
