These trick flapper valves provide 40% more airflow to the engine. They are activated by air box vacuum. As soon as the engine intake needs more air than the stock system can provide the Powder Valves™ open, delivering the required amount of air to the engine. This kit utilizes a Powder Snow Pre-Filter over the Powder Valve™ to keep water and snow out of the intake tract.
