  • 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.

    • Choose MaxFlow 5 Oiled Filter for improved performance with the comfort of oiled filtration technology for those looking for horsepower
    • Choose a DryTech Oil-Free Filter for improved performance without the need of regular maintenance and the benefit of maximum airflow

    Long wait but worth it.

    The holes don’t line up the best to the 4 runners factory holes but I got it in. Great air flow and improved MPGs. Took over a month due to their vendor supply issues but it’s worth the wait. I do wish they stated a lead time in shipping when you order the item and keep you informed on delays without having to inquire. Overall? I’d use them again without hesitation and I have suggested their products to others.
