Provided is a device used in the air induction tube of an internal combustion engine after the air filter and before the throttle body, and in particular to a device used to separate an air flow into a plurality of segments. The device can be made of two pieces. Each piece is initially a flat plate.
Provided is a device used in the air induction tube of an internal combustion engine after the air filter and before the throttle body, and in particular to a device used to separate an air flow into a plurality of segments. The device can be made of two pieces. Each piece is initially a flat plate. A slit is formed half way through each plate and the corners are cut off or clipped. Each plate is then formed to have two generally curved portions. The pieces are joined via the slits resulting in the device. The pieces are generally perpendicular to each other at their intersection. The device is fitted into the air induction tube upstream of the throttle body, whereby it separates the air flow into distinct segments. The curved walls can be slightly compressed when inserted into an induction tube to hold the assembly in place.
