For those that cover high mileage, or that just want to ensure their X3 remains performing at its best without the hassle of cleaning and re-oiling periodically, we're pleased to now offer the cotton gauze mountune Air Filter as a replacement standalone item.

A direct replacement for X3, and also similar enclosed induction systems on the market that use the same backplate dimensions, this air filter can also be used by those wishing to build their own induction system as it joins to the factory induction hose and PCV connection.

Backplate dimensions:

Width: 270mm
Height: 137mm

Compatible with R600 airbox.
