A good upgrade to OEM part for less money. Quick delivery and great service from sportsbikeshop as always.

Exactly what you’d expect

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!

Makes a difference

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.

K&N Air Filter KT-1217 - KTM

This is my first, K&N filter. My first impression was how well made the filter was, it was a perfect drop on my 390 adv as a replacement. I felt an improvement in throttle response and the bike felt a little quicker with no noticeable downsides.
