12V Cummins Cold Air Intakes

Cold-air intake kits for the 1989-1998 Dodge Ram 5.9L 6BT from S&B Filters and Banks Power. Increases air volume, reduces intake temps, and improves throttle response on first- and second-gen 12-valve trucks.

12V Cummins Intake Horns & Intake Manifolds

Dual intake horns and intake manifold upgrades from Wehrli Custom Fabrication and XDP. The factory single intake horn restricts airflow on modified 12-valve engines - a dual intake horn replaces it with a two-horn design that improves airflow balance across both cylinder banks. For additional 12V engine parts, see the 12V Cummins engine parts collection.

12V Cummins Intercoolers & Intercooler Pipes

Intercooler upgrades and charge-pipe kits for the 1994-1998 second-gen 12-valve trucks from Mishimoto and Fleece Performance. Reduces charge air temps under boost for more consistent power on modified engines.

12V Cummins Coolant System Parts

Coolant filters, thermostats, and coolant additives for the 12-valve 5.9L. For fuel system upgrades, see the 12V Cummins fuel system collection.

12V Cummins Intakes & Cooling - Frequently Asked Questions

  • Cold-air intake kits, dual intake horns, and intake manifold upgrades. Brands include S&B, Banks Power, Wehrli Custom Fabrication, XDP, Mishimoto, and Pusher Intakes.

  • Yes - the factory airbox restricts airflow at higher boost levels. A cold-air intake lowers intake temps, most noticeable on P-pump trucks with upgraded injection.

  • The factory single horn feeds both cylinder banks. A dual intake horn from Wehrli Custom Fabrication improves airflow balance with a two-horn design - one of the most common bolt-on mods on 12-valve trucks.

  • 1989 through 1998 in Dodge Ram 2500 and 3500 trucks. For 1998.5-2002 trucks, see the 24V Cummins parts collection.
