The K&N 63-1592 is a 63 Series AirCharger cold air intake built for the 6.7L L6 diesel in 2013-2018 Ram 2500 and 3500 trucks. It is engineered for the Ram 2500/3500 L6-6.7L DSL. A custom designed enclosed air box helps protect intake air from the high temperature of your engine bay. The tube is a high-density polyethylene part that the manufacturer rotationally molds for airflow volume.
Over stock, the case for this kit rests on published numbers. The manufacturer lists an estimated horsepower gain of 16.5 HP @ 2000 RPM and an estimated torque gain of 44 lbft, and says it requires no tune. The filter is washable oiled cotton rather than a disposable paper element, and dyno reports are included with each intake system. Towing buyers will also find the manufacturer's claims about improved acceleration and uphill performance when towing relevant.
Yes. The manufacturer's fitment listing shows the 63-1592 as fitting the 2018 Ram 3500 6.7L L6 diesel.
No. The manufacturer states the kit is not legal for sale or use in California on any pollution-controlled motor vehicle.
According to the manufacturer, K&N intakes are engineered to work with the factory tune, and no additional modifications are needed to get the listed performance gains.
The manufacturer says the complete system can typically be installed in less than 60 minutes with basic hand tools. The general K&N install guidance calls for disconnecting the mass air flow sensor connector, loosening the clamps, and removing the stock tube, then moving the MAF sensor into the K&N adapter before attaching the new intake tube to the throttle body coupler and securing the K&N filter with the supplied clamp. Watch the MAF sensor transfer closely, since it is the step most likely to cause a check-engine issue if the gasket or connector is mishandled. Owners on user forums commonly recommend checking every clamp and connection afterward for air leaks.
