• 【Dual Functionality】 This hose serves a dual purpose, functioning as both a PCV valve connection hose and an intake manifold vacuum line; it effectively vents crankcase blow-by gases and maintains pressure equilibrium within the vacuum system. It directly resolves issues—such as unstable idling, hissing noises in the engine bay, and oil vapor leaks—that are caused by aging components, thereby restoring the engine's fuel efficiency and power responsiveness
• 【Durable Material】 The 99071AD690 PCV valve hose kit is crafted from high-quality rubber, offering exceptional resistance to oil, high temperatures, and aging. Designed to withstand the complex, high-temperature, and high-pressure environment of the engine bay, it resists cracking, hardening, and deformation, providing a service life far exceeding that of ordinary hoses
• 【When to Replace】 Inspect the vacuum hose for any signs of cracks, holes, or deterioration due to aging. Additionally, performing a vacuum test can confirm whether the hose's seal remains intact. If you encounter issues such as fluctuating engine RPM or a loss of power, it is recommended that you inspect or replace the hose. Regular inspections help maintain your vehicle's optimal performance and prevent more costly repairs in the future
