Built for the 3.6L V6 in the Ram 1500, the K&N 63-1594 replaces the factory air filter and intake tube with one assembly. The tube is rotationally molded high-density polyethylene, and the filter is a large oiled-cotton element that can be washed and reused. The manufacturer's dyno chart for a 2021 Ram 1500 3.6L lists an estimated 9.31 hp and 17 lb-ft gain, which the company presents as estimates rather than guarantees. For towing and throttle response on a daily-driven truck, a complete tube-and-filter system is a stronger upgrade than a filter swap alone, and the washable element avoids recurring paper-filter costs.
Owners searching for a Ram 1500 3.6L cold air intake that stays reusable should note the manufacturer's service interval: the filter only needs cleaning every 100,000 miles under normal highway driving. The kit ships with stainless steel clamps and couplers, so the hardware is in the box. Fitment deserves a careful check before ordering. The manufacturer's product title lists 2020–2023 trucks, but its Ram 1500 intake page also lists this part number for 2024–2026 models, so confirm your VIN with the manufacturer before buying.

The manufacturer says typical installation takes around an hour and can be completed with simple hand tools. Count the clamps and couplers against the packing list before you start. Use the manufacturer's installation instruction sheet for routing and fastener order, and confirm the sheet matches your truck's model year before beginning.
