The DME Racing Oil Cooler Block Off Plate is designed to block off the oil cooler lines from the engine case and oil pan to the oil cooler.
Most aftermarket oil pans do not have a spot to mount the oil cooler line, so for those customers, you just need one block-off plate for the engine case.

What is the purpose of the Oil Cooler Block Off Plates?
Oil cooler block off plates are used to bypass or eliminate the oil cooler in a motorcycle’s cooling system. Using oil cooler block off plates on a motorcycle is typically not a common practice, a high-performance motorcycle is designed for speed and performance. The oil cooler plays a critical role in managing engine temperatures, especially during high-stress situations, such as high-speed runs or extended periods of heavy load.
However, using oil cooler block off plates does serve a specific purpose in motorcycle drag racing, such as:
Racing Modifications: In certain racing scenarios, riders might aim to reduce weight or simplify the cooling system to gain a slight edge in performance. Removing the oil cooler and using block-off plates could be part of modifications aimed at optimizing the bike for racing conditions.
Track-Only Use: For motorcycles used exclusively on the track where environmental conditions and extended cruising are different from regular street riding, some riders might consider modifying the cooling system. However, this modification should be carefully considered and tested, as it could affect the engine’s performance and longevity.
Customization: Some motorcycle enthusiasts might modify their bikes for aesthetic purposes or to achieve a specific look. Removing the oil cooler and using block-off plates could be done as part of customization, although it’s not commonly recommended due to potential implications on engine cooling.
It’s important to note that removing the oil cooler and using block-off plates may lead to increased engine temperatures, reduced thermal efficiency, and potential risks of overheating, especially during prolonged high-speed runs or heavy usage. It’s highly recommended to consult with an experienced mechanic or specialist who understands the specific implications for your engine before making such modifications. Additionally, riders should consider the potential impact on the warranty and overall reliability of the motorcycle.
