Core Function: The built-in spring and valve core enable low-flow ventilation during idle operation while providing high-flow ventilation under heavy loads, thereby maintaining stable pressure to enhance engine efficiency.
Product Material: Crafted from premium metal, designed to withstand high engine temperatures with exceptional wear and heat resistance.
Precise Compatibility: Exactly matches the N54 engine, allowing direct replacement of the old PCV valve. Installation is straightforward—no additional modifications or drilling required. Simply screw it in and it's ready to go.
Simple installation, DIY-friendly: ① Insert the spring and valve needle into the valve body, then tighten the internal components with the hex nut. ② Screw the PCV valve body (with O-ring) into the corresponding engine mounting hole. ③ Connect the PCV valve hose and ensure the clamp is secure.
