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, cold air is preferred.
Engine-Specific Fitment
The 2002–2010 Ram has multiple engines: 4.7L V8 2002–2008, 5.7L Hemi 2003–2010, and 5.9L 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 (Injen EVO Dry, Pro Dry-S) are maintenance-free longer. Injen EVO offers both oiled and dry options.
1500 vs 2500/3500
Some intakes fit Ram 1500 only; others fit 2500/3500. The 5.9L Cummins was available in 2500/3500. 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.

Injen Evolution is the dedicated cold air intake for 2003–2007 Dodge Ram 2500/3500 with 5.9L Cummins. It delivers +25 HP and +62 lb-ft with a dry filter.
