The BMW R 18 Stage 2 air filter kit adds power, torque and improves throttle response (includes Stage 1 DNA Air Filter). This system eliminates the restrictive, plastic OEM intake box with a specialty bracket that holds a high-performance DNA motorcycle air filter with a substantially increased surface area. Clean, efficient airflow is increased 44.87% over stock, allowing you to get the most horsepower and smoothest throttle response. The filtering efficiency is extremely high at 98-99% filtering efficiency (ISO 5011), with 4 layers of DNA Cotton.
Kit replaces the stock air box, no additional parts required, plug and play installation.
