Abstract
A throttle body for an air intake system of an internal combustion engine, which includes a combustion chamber. The throttle body includes a body, a throttle plate and a coating. The body defines a throat through which air flows to the combustion chamber. The throttle plate, which is pivotally mounted with respect to the body, moves between first and second configurations with respect to the throat. The first configuration of the throttle plate substantially prohibits the air flow through the throat, and the second configuration of the throttle plate permits air flow through the throat. The coating, which is on at least one of the throat and the throttle plate, sheds contaminants that extend between the body and the throttle plate in the first configuration of the throttle plate.
