ANTI-RAIN VALVE FOR EXHAUST 122/130 MM DIAMETER
The anti-rain valve, also called rain cap in English, allows you to close the vertical exhaust pipe when the engine is off. It therefore prevents water from entering the engine via the exhaust manifold, which can over time block the engine, but also cause water to enter the engine oil pan.
This anti-rain flap is adaptable to all exhausts having a round outlet with a diameter between 122 and 130 mm
