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

    LB7 Intake

    The intake pipe could have been bent better, the boots fit kind of okay, the way they went on upset my OCD, with the air cleaner installed, the lid doesn’t sit totally flush. I could only install box with two bolts instead of four. I can send pictures if you’re curious. I like the intake for the main reason of being able to run a power core air filter
