Air filter DNA RACING for original air box motorcycle Yamaha YZ 250 F, 400, 426, WR 250/426 F 1998/2002

This is the R-Y4E98-01 air filter for your Yamaha YZ 250 F, 400, 426, WR 250/426 F 1998/2002.

The flow rate of this DNA Fcd filter is high, more than the standard paper filter! This DNA filter is equipped with DNA's advanced Full Contour (FCd) technology. Filter installation is very easy, just follow the information in the YAMAHA Workshop Manual.

This DNA filter is designed as a high flow filter for on-road or off-road use. We all know that an original motorcycle runs a bit too rich original for better protection in conditions never reached in our countries (use of engines in countries very hot, bad gasoline low-end and old. ..).

This is why we can afford even with a carburation / injection of origin to opt for a freer air filter. DNA FILTER filters are washable filters that allow more air for better performance with poorer AFR ! They last the life of the bike because you just clean them and then re-oil them.
