  • Volant air intake systems utilize a high-velocity venturi filter adapter which provides a smooth transition through the MAF sensor into the intake tube for a much needed airflow improvement over the factory rubber tubing and resonator box. Volant's Cool Air box is larger than the factory unit and incorporates a larger opening to collect a higher volume of colder ambient air.

    Enhanced breathing

    This product is installed on an '02 CC 2500HD 6.0 with a performance free flowing exhaust. Now the problem with a free flowing exhaust is it can expel the gasses but the engine is like an Olympic runner running a race breathing through a straw, it's very restrictive and this product just opened up the intake of air so it can run better. Coupled with the lower air scoop to ram air into the air box providing a positive pressure so it's not ******* air at atmospheric pressure but rather cold air pushed into the engine. If you see how the other "cold air" systems work the air box isn't closed in so it's not a true cold air design, it still draws under hood heat from the engine bay.
