Filter Guide

Filter Options
  • 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.

    Filter Options Include:

    • Choose a PowerCore® for the best filtration on the market with 100,000 Maintenance Free Miles of Driving and perfect for hard conditions
    • Choose a Drytech Dry Filter for improved performance, easy soap and water maintenance, ideal for all cars and trucks
    • Choose a MaxFlow 5 Oiled Filter for improved performance with the comfort of oiled filtration technology for those looking for horsepower

    Bought for a 2004 8.1 Silverado

    Doesn’t fit worth a damn , tube to box doesnt fit over the throttle body . Finally got it half assed on . Doesn’t line up remotely close to the air box even if you cut the tube like they say to . Currently using the stock intake tube with the volant box . Also lid doesn’t fit . Holes don’t line up .

    Havent gotten to use it

    Havent gotten to use it yet. Got complete system and had to file warranty claim because filter hole was cut wrong on air box. That was 4/30/21. Filed claim a day after. Received email stating they would send out a new air box. Had to call because i had not received said air box yet and this was 5/9/21. It had not shipped for some reason but was supposed to ship out on the 4th. Looks great but have not used yet. Shipping and communication could definitely be better.
