The intakes in this section are for diesel engines only. Volant Diesel Intakes are available with the Primo Filter or the ALL NEW PowerCore™ dry filter. The Volant Primo air filter has more layers of filter media to compensate for the intense intake vacuum created by diesel engines, so you know you’re giving your diesel the special treatment it deserves. The New Powercore utilizes NanoFiberSM technology, allowing submicron contaminants to load on the surface rather than collecting in the depth of the filter. This boosts efficiency and increases performance for your aftermarket intake system. Ultra-Web® NanoFibers™ won't deteriorate as easily as traditional filters. Plus, it's water resistant, so getting wet won't ruin your flow or ever cramp your style. This is why we warranty our replacement PowerCore™ air-filters for 4 years or 100,000 miles.
