I have a Fram Boost on my Titan wich is the same as the AEM and I have a Volant Powercore on my Dodge Cummins. The volant has the Donaldson Nano fiber filter which is the same filter used on the Abrams over in Iraq and If I was to buy another CAI for the Titan it would be the Volant. 4 year or 100,000 mile guarantee, it's enclosed which seals out the engine heat, it's water proof and needs no special cleaning solution or oil. VOLANT
