HiFlo air filter for your Yamaha YP400 Majesty (2nd Air Filter) year range 2004-2012 and Yamaha YP400R X-Max (2nd Air Filter) year range 2013-2018. The type number of this air filter is HFA4405.

HiFlo air filters are made of high-quality materials and are made according to ISO standards and are also regularly checked for correct operation and quality by the German TÜV Süd. Furthermore, the air filters meet the requirements set by the motorcycle manufacturers. Replacing the air filter of your Yamaha YP400 Majesty (2nd Air Filter) year range 2004-2012 and Yamaha YP400R X-Max (2nd Air Filter) year range 2013-2018 is relatively easy to do yourself and no adjustment is required to the adjustment.

Please note: It is a misunderstanding that K&N provide better performance because they have a higher air flow. It is indeed true that they allow air to pass through better than HiFlo or original brand air filters. However, this is detrimental to the petrol/mixture if the motorcycle is not adjusted differently. The problem is that this reduced air resistance of K&N and BMC air filters creates negative pressure. This underpressure causes the mixture to become leaner and the combustion temperature to rise, which can be harmful to your motorcycle. This will certainly lead to poorer running of the motorcycle, especially in carbureted motorcycles (injection motorcycles with a Lambda probe largely correct this themselves). With HiFlo, the manufacturers' specifications are adhered to, so readjusting your motorcycle is not necessary, as is the case with K&N air filters.
