Simply relax, take your time and make sure it's right! All we ask is that you try the items within your own home and return with the tags intact.

As retailer of the year, we feel it's our duty to constantly better our offering and if you have any ideas, we'd love to hear from you!

You can aways trust K&N

Nice snug fit into the air box of my 2008 Fazer S2. Thanks to the lockdown I haven't had the chance to ride the bike since it's been fitted. But no issues with fitment and having used K&N in the past on my cars, I know there will be no issue!

Air filter was delivered with loads of sand and grit stuck to it. I had to remove as much as I could before fitting. Once clean and in the bike ticks over much better and sounds a little better to.
