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 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.

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.
