Review on Enhance Your Dodge/RAM's Power: K&N Cold Air Intake Kit (2009-2019 5.7L V8) – 77-1561KP by Jeremy Romero

Installed on a 2016 Ram. Installation is very easy, instructions are not well written.> Before installing this unit, I drove 450 miles for a week under controlled conditions and tracked mileage/fuel consumption with both trucks integrated into the system and Scan Gauge 2 with firmware. rev 4.5 > After installation I have also been driving under the same controlled conditions at the same miles/rpm etc. E. I've concluded that this unit from KN actually reduced the mpg by 7%.> Also note that this system does absolutely nothing about the initial acceleration lag caused by the drive-by-wire system in the truck inherent. All other acceleration claims are wishful thinking. Remember that noise doesn't mean better performance. This unit is a bit noisier than the standard air filter, however, when comparing the available area of the KN replacement filter to the standard air filter, it is not much larger. In summary, the buyer should be careful. K&N has a fine print page that essentially disputes all of the stated claims on the box. Apparently if there is a boost you need to hit 4500 rpm or higher to get it.
