The only point to bear in mind is this K&N filter is specified by K&N for a vast number of H-Ds, from Twin Cams to Sportsters as well as being listed for M8s, however the OEM filters for these various models are not the same or same size!
I've used the K&N UK link however the US site has the same detail!
