Info from design 911
Replace your restrictive air box and filter with a PowerFlow kit for improved air volume and velocity, and increased horsepower. A better breathing engine also gives you faster throttle response. Each design has been flow bench and engine dyno tested to assure maximum performance. PowerFlow kits include the PowerFlow intake unit, lifetime air filter, instructions, and all hardware.
Cooler air = MORE POWER + 8-10BHP.
Cone filters have superior air flow characteristics as compared to flat panel filters. The cone filter better structures the air as it enters through the filter and the additional intake length and shape of this system further increases air flow for smoother straighter more formed air.
