Airaid SynthaFlow CAD (cold air dam) intake systems supply your engine with maximum cold airflow for maximized performance! Their cold air dam design isolates engine heat away from your intake to keep the cold air flowing. Airaid CAD intakes feature SynthaFlow filters that are hand-made from multi-layered cotton gauze and the finest synthetic materials to trap the smallest particles of dirt. These oiled filters are washable and reusable and only need to be serviced every 30-50,000 miles, depending on the environment. The SynthaFlow filter is built with a hand-poured urethane body that won't crack, curl, or shrink like competitors' filters. Airaid SynthaFlow CAD intake systems use the stock air filter location, but add a boost with a huge air inlet that keeps more cold air flowing through the 360 degree filter. These systems maximize your horsepower, torque, and fuel efficiency. They seal directly to the hood and include all parts needed for an easy installation.
