The GATES EMH718 is a high-quality hose engineered for the crankcase ventilation system. This component plays a crucial role in managing the gases produced within the engine's crankcase, preventing pressure buildup and directing them to be re-burned. Proper functioning of the crankcase ventilation system is essential for engine longevity and performance. It helps to reduce emissions by ensuring that blow-by gases are recirculated and not released directly into the atmosphere. The GATES EMH718 is built to withstand the demanding conditions within the engine bay, ensuring reliable operation. Replacing a worn or damaged ventilation hose with the GATES EMH718 can help restore optimal engine performance and prevent potential issues such as oil leaks or increased oil consumption. This part is designed to meet or exceed original equipment specifications.
