Upgraded PCV valve

A replacement PCV valve for both boosted and naturally aspirated cars. Deals with boost better than the stock parts. Direct replacement for NA models and the Mazdaspeed. Other NBs can use it if the hose is changed - there's an appropriate hose in NAPA part NOE 6002774. Note that this is very similar to the factory unit for the Mazdaspeed, so it should be considered a replacement instead of an upgrade for that car. Show more
