Air filters for motorbikes (made by K&N - USA)

K&N's special material permits more air flow to the engine than stock filters, with no loss of filtration efficiency.
K&N air filters last practically forever.
Air filters come ready to use.
Use the K&N air filter cleaning kit. For higher efficiency, we recommend that K&N air filter kits be installed with the associated Dynojet carburettor kits or Dynojet Power Commander units.
If used without the associated Dynojet carburettor kits or Dynojet Power Commander units, K&N air filters will improve engine breathing but will not increase power output.
If K&N air filters are used on carburettor bikes without the associated Dynojet carburettor kits, jetting must be delayed reset by increasing main jet size by approximately 2 to 4 points to ensure correct engine operation. On injection bikes, the stock management system usually makes up for everything with no need of intervention.
