DME Racing’s Billet Single Throttle Body Plenum is precision-engineered for high-horsepower drag racing applications. Designed to smooth out pressure differentials, this plenum transforms low-pressure pulses into a steady, continuous airflow wave—delivering consistent, powerful performance. Without a proper plenum or with one too small, air pressure can fluctuate, causing airflow to reverse through the restrictor and reduce performance. Our large-volume plenum eliminates these issues, ensuring stable airflow and maximum horsepower. Race-proven in the most demanding conditions, this plenum has powered motorcycles to 6.30-second, 240 mph runs on the quarter-mile.

What is a Motorcycle Plenum’s Purpose? The Intake Plenum is a part of your motorcycle’s intake manifold. The primary function is to transfer the fuel-air mixture to the cylinders. During the fuel distribution, the pressure in the manifold should be higher than that in the cylinders during their intake stroke. The intake plenum’s function is to produce this high pressure. It is basically a pressurized air enclosure. The manifold has a row of individual tubes called runners that extend out of the plenum. They supply air/fuel mixture to the respective cylinders. The runners occupy a smaller area of the plenum surface.
