With the Volant Cold Air Intake System you can increase performance up to 18 horsepower, add 40 lbs of torque and even save gas mileage. The Hi-Flow Velocity Air Box breathes in oodles of performance-enhancing air via the massive air duct. Many Volant Cold Air Intakes also include an enclosed air box that takes power and efficiency higher. Some drivers even report an increase in gas mileage by 1 to 2 miles per gallon. What’s more, it can take less than an hour using standard household tools to replace the old, suffocating factory air box. Volant gives most vehicles a performance filter choice: the original high-performance cotton-gauze filter with cleaning intervals of 35,000-50,000 miles.
