Banks Power 07-09 Dodge 6.7L Ram-Air Intake System - Dry Filter
The Banks 42175-D is the Ram-Air cold air intake with a dry filter element for 2007 through 2009 Dodge Ram 2500 and 3500 pickups with the 6.7L Cummins. These were the first model years of the 6.7L, and many of these trucks now tow on a factory air box that has been opened, patched and fed paper elements for well over a decade. Buyers usually come looking for lower exhaust gas temperatures on long pulls, less black smoke, or simply a sealed, washable filter that they never have to oil.
The 6.7L makes its power with a variable geometry turbo, and every pound of boost starts as air pulled through the filter. Banks replaces the stock housing with an enclosed box, a large dome-shaped element and a smooth intake tube that runs to the compressor inlet through a short coupler. Banks rates the system at up to 50 percent less restriction than stock and quotes gains of up to 28 horsepower and 52 lb-ft with lower EGTs. Treat those as the maker's figures; the result most owners actually notice is cooler pyrometer readings when loaded. The box draws outside air instead of under-hood heat, and a 4-1/2 inch bellows lets the engine rock on its mounts without stressing the tube.
The 07-09 kit uses its own housing, Banks part 42176, shaped for the earlier trucks. The 2010-2012 kit uses a different housing, so the two are not interchangeable even though the tube, cover and most hardware are shared.
An intake will not fix a tired transmission. If your truck is flaring between gears, slow to engage or going into limp mode, read our 68RFE Ram 2500 Cummins common problems guide before spending money on airflow.
Pop the hood and check the engine badge and the air box: this kit replaces the factory 6.7L box mounted on the radiator core support and battery tray bracket. Look for a filter minder (restriction gauge) in the stock lid, since the Banks cover accepts it and a plug is supplied if your truck never had one. If your 2007 has the 5.9L, this is the wrong kit. The 2007 model year was the changeover, and our 48RE vs 68RFE guide helps confirm which engine and transmission package you have.
Listed for 2007-2009 Dodge Ram 2500 and 3500 pickups with the 6.7L Cummins diesel. Banks covers this kit and the 2010-2012 version in one manual written for pickup trucks, so cab and chassis models should be confirmed with us first. If your truck is a 2010 or later, use the 42180-D for 2010-2012. California buyers: CARB Executive Order D-161-102 names 42175-D for 2007-2009 Ram with the 6.7L, but the copy on the ARB site is stamped rescinded, so verify the current status before installing on a smog-checked truck. Not sure? Send us your year and VIN. Transmission parts for these trucks are in our 68RFE collection.
To clean the dry element, Banks says to spray on a dry air-filter cleaner, soak about 10 minutes, rinse with cool or warm water from the clean side out and let it air dry. Street trucks can go 50,000 to 100,000 miles between cleanings. Pair it with the Banks 25990 boost tube system for the pressure side, and if you tow hard, a fresh 68RFE filter kit is cheap insurance.
