ABSTRACT:
An air induction system (10) for use with an internal combustion engine which includes a throttle body (24) mounted to an intake manifold housing (12). The manifold housing (12) includes an incoming flow passage (20) and a series of annular grooves (32). The annular grooves (32) are located between the throttle plate (30) and the incoming flow passage (20). These grooves (32) create turbulence in the air stream for improved performance under certain engine operating conditions and also act as moisture and contaminant traps.
