The increased airflow with the power filter means that you may need to install larger main jets in your carburettors. Alternatively, you can increase the airflow through the original jets by gradually enlarging them with a jet reamer kit. Some technical experience is needed for this job!
The world's best air filter!
Economical: never change another filter! Once you replace the standard air filter with the K&N permanent air filter, it will last as long as your bike. The standard carburettor and air filter housing configurations remain the same. Registration of the modification in the vehicle document is not necessary. Sporty: the K&N permanent air filter boosts power as better airflow means fuel and air is mixed more quickly. The engine responds more spontaneously when the throttle is opened and the faster filling of the cylinders is translated into better acceleration. K&N permanent air filters get the most out of your engine.
These power air filters are compatible with many motorcycle models, but they are not E-marked and do not come with type approval, TÜV test certificate or any other form of official approval. This means they are not street-legal under the German Road Traffic Licensing Regulations (StVZO). They must only be fitted and used for racing, competition and show purposes (classic and collectible motorbikes). Before they are used on public roads, it is obligatory to first take them to your local test centre (TÜV in Germany) for individual component approval. We give no guarantee that such individual component approval will be possible. Please also note the information we provide regarding the relevant approval regulations (Item III), e.g. in our Standard Terms and Conditions, also for use outside of Germany.
