An engine's power output is proportional to the rate at which it can induce air into the cylinders, and the torque output is directly proportional to the amount drawn into the cylinders on each induction stroke. All but the most minute restriction will cause an engine's power output to drop. Conventional paper elements and synthetic foam filters are generally restrictive in terms of airflow and deteriorate relatively quickly and cause power output to drop further.

Running without air filters is definitely not an economical option as engine life is drastically reduced. K&N air filters provide the best solution.

The filter utilizes an accordion fold design to provide up to 5 times the normal filtering surface of non-pleated filters.

The K&N solution provides your engine with better protection and lets it breathe easier to improve power and torque. Cleaning is recommended once a year or when heavy deposits have built up, the air filters are washable and guaranteed for life.
