These vents provide cold air inlet and hot air escape from the chassis for cooler underhood temperatures which helps maintain higher horsepower. They feature our new Max Flow™ 2.0 air vent technology. This new air vent technology utilizes injection molding to encapsulate a new durable stainless steel mesh to act as a protective shield for our famous water repellent pre-filter material. The combination of these two materials incorporated in one vent provides great durability while maximizing air flow through the chassis and keeping snow out. New as well with this Max Flow™ 2.0 technology are sightless fasteners for an extremely clean look, to more readily shed snow and increase strength. These vents are unmatched in quality, function, appearance and durability.
