The K&N 63-1701 is a cold air intake for the 3.0L V6 turbo diesel in Sprinter 2500 and 3500 vans from 2013 to 2018. K&N forms the intake tube from roto-molded cross-linked polyethylene and pairs it with an oversized oiled cotton filter. An enclosed air box keeps that filter shielded from underhood heat, so the system suits owners who want a dedicated diesel air path that outperforms a stock box-and-filter setup.
K&N says the system is guaranteed to add horsepower and torque, and its dyno chart for a 2016 Sprinter 2500 3.0L shows a 7.6 HP gain. That is a single-vehicle result, not a universal figure. The filter is designed to go about 100,000 miles between cleanings under normal highway driving, which is a practical reason to pay for an oiled cotton element over a disposable paper filter. Enthusiasts searching for a Sprinter 3.0 diesel cold air intake, a 2500/3500 V6 TD intake upgrade, or a K&N 63-1701 install guide will find the fitment and install details below.
The manufacturer states it is not legal for sale or use in California on any pollution-controlled motor vehicle. Check your state's emissions rules before ordering.
The manufacturer's listings for this part number include 2013–2018 Sprinter 2500 and 3500 3.0L V6 diesel applications. Its 2500 listing also shows 2010–2012 entries, so details vary. Confirm your exact year and VIN with the manufacturer before buying.
The manufacturer says the oiled cotton filter only needs cleaning about every 100,000 miles under normal highway driving conditions.
Plan on 60 to 90 minutes with basic hand tools. The manufacturer's install sheet lists a ratchet, extension, 7mm, 8mm, and 10mm sockets, a T20 Torx bit, a 5mm Allen key, a flat-blade screwdriver, and pliers. Start by disconnecting the negative battery cable. Then unplug the mass air sensor and the sensor connectors, release the factory air filter housing harness, and loosen the clamps to pull the stock tube. Fit the K&N tube and mass air sensor assembly into the couplers, adjust for the best fit, and secure everything with the provided hose clamps. Take care when routing the sensor wiring so nothing rubs against the new tube.
