Having trouble getting your 5.0 to idle at the rpm you want? This handy little idle bypass valve lets you adjust the idle speed without turning the throttle stop. Since it doesn't change the throttle angle, you don't have to reset your TPS sensor voltage every time you adjust the idle. So you spend less time chasing the idle speed and more time enjoying your ride.
