Our new intake kit for the 6.4L demonstrates a 23.3% increase in air flow over the stock intake while still maintaining a 99.51% efficiency level with an oiled filter. The dry filter produces a 21.5% increase in air flow and is 99.59% efficient when tested at 593 CFM. Easy to install with a fitment that rivals the OE intake. Securely mounts to the stock location.
 
Generally, installs take 30 minutes or less.When its cool out, remove the included plug from the secondary box opening, and engulf an insane amount of air. With the secondary port open, air flow is increased by 6.9% with a cleanable filter and 4.9% with a dry filter.
