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.
This model includes a MaxFlow 5 Oiled Filter for improved performance with the comfort of oiled filtration technology for those looking for horsepower.

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.
We won't bother you too much, but sometimes we have some cool stuff to talk about...
