Windage Tubes are the fastest and easiest way to reduce oil sloshing and leaking valve cover gaskets. The extended neck of the Windage Tube fits snugly into the engine case to help keep engine oil where it belongs. Windage Tubes are designed for fast, easy installation; you just bolt 'em in just like stock push rod tubes. The difference is in the performance. Off-road, street and all-out competition engines will run stronger and longer with controlled oil flow. Windage Tubes can also reduce engine temperature by transferring internal engine and oil heat to the outside airflow. Windage Tubes fit all 1500, 1500 and 1600 based engines. They are shipped complete in sets of 8.
