Can’t go wrong with a K&N filter give it a good clean every couple of thousand miles if ya want. And use the proper cleaning chemical and oil works a treat.

K&N Air Filter TB-1216 - Triumph K&N Air Filter TB-1216 - Triumph
Super easy to fit. Came with grease to ensure a good seal round the edges. Probably gave an extra HP or two in combination with new exhaust and ecu flash compared to keeping the stock filter. For £50 no reason not to!

K&N Air Filter HA-3021- Honda CRF300L / CRF300 Rally K&N Air Filter HA-3021- Honda CRF300L / CRF300 Rally
Bought one to replace the stock part fitted to my CRF300L. This instantly made a difference, enabling the engine to breath. Bike now seems to run better and even seems perkier on acceleration.
