MX5 PCV-valve crankcase ventilation

A PCV-crankcase ventilation valve for your Mazda MX5 NC (2005 - 2015) suitable for the 1.8l and 2.0l engine.

This valve allows non-burnt gasoline to be redirected back into the intake manifold. So that it can be utilized again. The piston rings never seal 100%, so there is always a small amount of unburned fuel left behind. Thanks to this valve, that fuel is reused. This contributes to more efficient combustion.

A faulty valve can lead to incorrect pressure ratios in the engine, which can cause problems such as higher fuel consumption, power loss and irregular engine performance.
