  • 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.

The intake was easy to install and it was exactly as advertised. It’s hard to believe but I boosted my MPG to 21.2 from 17.4. Very happy so far.

CAI for 21' Silverado 5.3

Install was fairly easy.. the connector hose from the box to the intake tube could have been about 2" longer and it would have been perfect but I got it to work. Going off of the CPU on the truck it shows I gained roughly 1.5 MPG with my normal driving...but it is a Trail Boss so I didn't really get it for great fuel economy. Overall i am very happy with the product. Thank you
