What to Know Before You Buy
Cold Air vs Short Ram
A cold air intake draws air from outside the engine bay for cooler, denser air and better power. A short ram intake stays under the hood; easier install and lower cost, but can pull warmer air. For maximum gains on a heavy-duty truck, cold air is preferred.
Engine-Specific Fitment
The 2019–2026 Ram 3500 has multiple engines: 5.7L Hemi (all years), 6.4L 392 (optional), and 6.7L Cummins diesel. Each requires a different intake. Verify fitment for your engine before buying.
Filter Maintenance
Oiled filters need periodic cleaning and re-oiling. Dry filters (S&B Dry Extendable, aFe Pro DRY S) are maintenance-free longer. S&B offers both oiled and dry options for 6.4L and 6.7L.
2500 vs 3500
Most intakes for 6.7L Cummins and 6.4L 392 fit both Ram 2500 and 3500. The 5.7L Hemi intakes fit 1500, 2500, and 3500. Check product listings for your specific truck.

Common Questions
Frequently Asked Questions
Do I need a tune when installing a cold air intake?
Most cold air intakes are plug-and-play; no tune required. The factory MAF sensor and ECU handle the increased airflow. For heavily modified engines, a tune can optimize gains. Check the product listing for manufacturer notes.
Will a cold air intake void my warranty?
Bolt-on intakes generally do not void the vehicle warranty. They do not alter emissions equipment. Some dealers may flag modifications; check with your dealer if concerned. Magnusson-Moss Warranty Act protects against blanket voiding.
