The piping is made of high-quality, oil- and corrosion-resistant materials. It can withstand the harsh environment of the crankcase for extended periods, resisting hardening, cracking, or deformation, ensuring long-term stable operation of the PCV system Both ends of the piping are equipped with original factory-spec quick-connect clips. To install, align the clip with the connector and push it in; a "click" indicates it is locked in place. To remove, press the clip to release the clip and gently pull it out Installation steps: Locate the original PCV pipe (usually located between the engine valve cover and the intake manifold), press the clip to remove the old pipe, clean any impurities from the connector, align both ends of the new pipe with the connector, and push it in to lock. No glue or sealing tape is required It is recommended to replace both sides of the piping simultaneously. The lifespan and aging rate of the piping on both sides are similar; replacing one side may cause the old pipe on the other side to fail soon afterward. This kit includes both sides of the piping, completing the repair in one step The package contains one left-side PCV pipe (12670791) and one right-side PCV pipe (12670793), for a total of two pieces.

After installation, start the engine, check for any air leaks at the pipe joints, and confirm that the idle speed is stable
