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. Customers using the Volant CAI kit with the scoop report 2-4 MPG improvements in fuel economy, as well as dyno-proven horsepower and torque increases. Volant is the first air intake company to properly apply a functioning Cool Air Scoop to a sealed air intake box. This model includes a Primo filter which gets reoiled every 10,000 miles and serviced every 50,000 miles with cleaning kit P/N 5110.Details: Cross Link Polyethylene Material Cleanable Reusable High Grade Filter High Temperature Silicon Connectors Stainless Steel Clamps 5 Layer Cotton Gauze Deep Pleats Increased Air Flow Filter Type:Oil Washable:Yes Filter Part Number: 5119 Fits:09-11 Chevrolet Avalanche 1500 5.3L V8 09-13 Chevrolet Silverado 1500 4.8L/5.3L/6.0L V8 09-13 GMC Sierra 1500 4.8L/5.3L/6.0L 11-13 Chevrolet Silverado 1500 6.2L V8 11-13 GMC Sierra Denali 1500 6.2L V8
