K&N ENGINEERING: RK Series and Street
Metal Air Intake Systems "provide
increased horsepower and torque for
Harley-Davidson motorcycles,"
according to the Riverside, California
cotton-gauze filter specialist. "The
popular kits each have a custom backing
plate that fits onto the stock throttle
body or carburetor. The backing plates
are made from powdercoated aluminum
and designed to provide solid mounting
and increased performance. These
systems also include a tuned velocity
stack to help direct airflow into the
engine for better performance. Oil
channels incorporated into the backing
plate direct crankcase vapor and oil
from the breather bolts back into the
engine"; www.knfilters.com
