Diesel Oil Filter
  • 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 MaxFlow 5 Oiled Filter for improved performance with the comfort of oiled filtration technology for those looking for horsepower

    Surprising easy in camparrison to the AFE stage 2 intake I previously installed. But the best part was the smooth off idle power I gained with it
