Banks Power 94-02 Dodge 5.9L Ram-Air Intake System - Dry Filter
The Banks 42225-D is a Ram-Air cold air intake with a black, washable dry filter for 1994-2002 Dodge Ram pickups with the 5.9L Cummins, the second-generation trucks that carry both the 12-valve and the 24-valve engine. Owners usually look for it when the old flat panel filter box is cracked or brittle, when exhaust gas temperatures climb on a long pull with a trailer, or when they have turned up the fuel and want to clear up the smoke that follows.
From the factory these trucks breathe through a flat panel filter in a plastic box, with a lid and tube running to the turbocharger compressor. The Banks kit removes the box, lid and tube and puts a sealed housing in the same spot, with a large conical filter inside, a new CFD-shaped intake tube and a fresh compressor inlet hose. Banks rates the system at up to 33 percent more airflow than stock. Less restriction ahead of the turbo means it reaches boost with less work, which is where the cooler EGTs and lighter smoke come from. The enclosed housing keeps the hot air from the engine bay out of the filter.
The dry element (Banks 42188-D) needs no oil. It is cleaned with a dry filter cleaner and water, so there is no oil film to wipe off the inside of the intake tube later.
Low power with normal EGTs and clean air is a different problem. On automatic trucks, a flare between gears or a 3-4 shift that slips under load is the transmission, and more air will only make that worse. Our 47RE Ram 2500 Cummins problems guide covers the usual failures on these trucks.
Open the stock box and look at the lid seal and the clamp at the turbo inlet. Dust on the clean side of the filter or inside the tube means the old box is leaking and should be replaced either way. Check the compressor inlet for oil, since a wet inlet points to turbo or crankcase venting issues that a new filter will not fix. Most important: if the truck has a Banks Brake exhaust brake, stop here. Banks states this Ram-Air system cannot be installed on a vehicle with the Banks Brake.
Listed for 1994-2002 Dodge Ram pickups with the 5.9L Cummins diesel, which matches the Banks owner's manual (96491) for kits 42225 and 42225-D. CARB Executive Order D-161-102 lists 42225-D for 1994-2002 Dodge Ram with the Cummins 5.9L, but the posted copy of that order is stamped rescinded, so California owners should confirm current status before buying. It does not fit the 2003 and later common rail trucks, which use a different Ram-Air kit. If you are unsure which engine you have, send us the year and VIN. If you prefer a red oiled element, see the 42225 oiled filter version. Automatic transmission parts for these trucks are in our 47RE collection.
Banks lists 50,000-100,000 street miles between dry element cleanings, or a change at 18 inches of water on a restriction gauge. If the truck tows, a 47RE transmission cooler and the 47RE pan, drain plug and filter kit are worth doing at the same time; our 47RE towing upgrades guide explains why.

It is listed for 1994-2002 Dodge Ram pickups with the 5.9L Cummins, which covers the 12-valve trucks and the 1998.5-2002 24-valve trucks. It does not fit the 2003 and later common rail trucks.
No. Banks states this Ram-Air system is not compatible with the Banks Brake exhaust braking system. If your truck has one, do not order this kit.
No. The black dry element is never oiled. Clean it with a dry air filter cleaner, rinse from the clean side out with cool or warm water and let it air dry before reinstalling.
It is a bolt-in swap with basic hand tools: a 10mm socket, Phillips screwdriver and 5/16 inch nut driver. The stock box, lid and tube come out and nothing is cut or drilled.
Only if the restriction is on the intake side. If the truck has normal EGTs but the transmission slips or flares between gears, look at the 47RE first. More airflow adds load to a tired transmission.
