    I have just picked up my 2019 CRF250L and the first thing I want to do is put on a k&n filter. Having looked on various sites it appears to be the HA-2513 which goes up to 2018.

    Before I order can anyone confirm the 2018 filter will fit the 2019. As far as I can gather not much has changed from model to model so it should fit

    I personally wouldn't install a K&N filter on a dirt bike. I have seen test results on another motorbike forum that I belong to and they performed the worst. I wouldn't put one on my street bike either. OEM paper or foam filters work much better. The K&N allows too much fine particulate to flow through causing damage to the engine over time. YMMV.

    I've seen the same evidence - K&N lets more particulate through. So it breathes better but may let junk into the motor. I've used HiFloFiltro filters on my bikes with good results - cheaper than the OEM and higher test ratings.
