The K&N 77-1586KC is a cold air intake built for the 3.6L Pentastar V6 in the 2019 to 2021 Ram 1500. It replaces the factory airbox and intake tube with a mandrel-bent aluminum tube and an oversized, washable oiled-cotton filter. The manufacturer estimates a gain of 13.45 HP and 11.1 lb-ft of torque, and it says the filter only needs cleaning about every 100,000 miles under normal highway driving. That makes it a practical step up from the stock paper filter for owners who want better throttle response, a deeper intake note, and fewer filter replacements. Owners searching for a 3.6L Ram 1500 cold air intake, K&N 77-1586KC install, or Pentastar V6 intake upgrade will find this kit built for that engine rather than a HEMI kit adapted to fit. The install is a bolt-on job with basic hand tools, which keeps it a realistic driveway project.
The manufacturer's 3.6L Ram 1500 listings for this kit cover the 2019, 2020, and 2021 model years. Ram 1500 Classic models are listed with a different filter reference, so confirm the year, trim, and engine against the manufacturer's application guide before ordering.
The manufacturer states the washable, reusable filter only needs cleaning about every 100,000 miles under normal highway driving conditions. Driving in dusty conditions will shorten that interval.
No. The manufacturer states this kit is not legal for sale or use in California on any pollution-controlled motor vehicle.
The manufacturer lists an installation time of roughly 60 to 90 minutes using a ratchet, extension, 10mm socket, 4mm Allen wrench, and a flat-blade screwdriver. Owners on user forums report finishing a comparable 3.6L kit in a little under an hour. Take care when removing the factory intake housing near the throttle body, since owners on user forums note that the stock plastic is rigid and can split if twisted off. Disconnect the battery before starting, and make sure the hose clamps are fully tightened on the couplers so the system does not leak unmetered air.
