Product description

Every motor needs ventilation. If the engine did not have ventilation capacity, the accumulated pressure would be expelled at the weakest point such as the seals, retaining rings, oil filler cap, etc. The higher the engine power, the better the ventilation should be.

Whether the motor is fully standard or high performance, the crankcase ventilation must be filtered, the intention is not for dirt to enter the crankcase.

At the factory, the crankcase ventilation is connected to the air filter. When you are going to fit a sport air filter, you may want to consider having the crankcase filtered by a separate filter, this way you save the air filter. For performance engines, the filter area will need to be larger and a separate filter is no longer sufficient. The best solution is to connect it to the air filter and, in case of double carburetor on both filters.

Not all air filters come standard with a housing breather fitting or mounting hole for this, if this is the case, you will need to drill a hole to make a connection.

You can choose between a plastic connection and, for the professionals among us, a stainless steel connection. The plastic fitting is only available in a 90° version, while with the stainless steel version you can choose between a straight fitting or a 45° or 90° angle fitting depending on the route of the ventilation pipes.

The plastic version requires a little less space and a reduced flow, the stainless steel connections are a little more robust with maximum flow.

The air filter for which the respective connection can be used ex works or as an additional option is indicated. Also refer to the specifications if you wish to mount the breather connection to your existing air filter, due to the space required for the hole you have to drill.
