Cold Air intake kit For 1994-2002 Dodge RAM 2500/3500 5.9L V6

Flashark Cold Air intake kit For 1994-2002 Dodge RAM 2500/3500 5.9L V6 Diesel Engine

The stock intake on a 1994-2002 Dodge Ram 2500/3500 with the 5.9L Cummins is a plastic airbox holding a paper panel filter. It's quiet and it's cheap, but it's also a restriction. The paper filter clogs over time, the plastic airbox traps engine bay heat, and the intake tract ahead of the turbo is starved for cool, dense air — exactly what a diesel needs to keep EGTs down under load.

The Flashark Cold Air Intake Kit replaces the factory airbox and paper filter with a high-flow dry-cone filter housed in a heat-shield enclosure. A silicone coupler and stainless steel clamp connect the filter directly to the factory intake tube — the metal pipe that runs from the turbo inlet to the airbox. The factory tube stays in place; only the restrictive airbox and paper filter are replaced. No replacement pipe is included or needed — this kit targets the source of the restriction without adding unnecessary components or cost.

Key Features

Heat Shield Enclosure — A formed metal shield surrounds the cone filter, isolates it from hot engine bay air, and seals against the closed hood. Pulls cooler, denser air from the fender well area rather than heat-soaked underhood air. Cooler intake air = lower EGTs and more consistent power, especially when towing.

High-Flow Dry Cone Filter (Red) — Washable, reusable, oil-free. Dry media means zero risk of oil fouling the MAF or IAT sensor. More surface area than the flat paper panel it replaces, so it flows better and clogs slower. Captures fine dust and debris — critical for trucks that work for a living.

Silicone Coupler + Stainless Clamp — High-temp, 4-ply-reinforced silicone coupler connects the filter to the factory intake tube (the metal pipe running from the turbo inlet to the stock airbox location). Stainless steel clamp ensures a tight, leak-free seal that won't loosen from heat cycling or vibration.

Bolt-On Installation — ~30 Minutes — Remove the factory airbox, install the heat shield using existing bolt holes, slide the coupler onto the factory intake tube, clamp on the filter, and position the shield. No cutting. No drilling. No tuning. Hand tools only.

Lower EGTs Under Load — The single biggest real-world benefit. By pulling cooler air through the heat shield enclosure, combustion chamber temperatures drop. This directly reduces EGTs during heavy towing, long grades, or running a performance tune.

Turbo Sound + Intake Growl — Removing the factory muffled airbox reveals the sound of the Cummins breathing — audible turbo spool, deeper intake note under throttle, and the mechanical character a diesel truck should have had from the factory. Not obnoxiously loud at cruise.

Package Includes

1 × High-flow dry cone air filter (red, washable/reusable)
1 × Heat shield enclosure (powder-coated steel)
1 × Silicone coupler (high-temp, 4-ply reinforced)
1 × Stainless steel hose clamp
1 × Mounting bracket with hardware (bolts, washers, nuts)
1 × Rubber edge trim (for heat shield)
1 × Installation instruction sheet
Note: This kit replaces the factory airbox, paper filter, and intake snorkel. The factory intake tube (from turbo inlet to airbox) is retained — simply disconnect the airbox end and connect the provided silicone coupler + filter. No intake pipe is included or needed.

A Cold Air Intake System repositions the air filter outside the engine bay to ensure the intake of the coolest air possible. Cooler air is denser in oxygen, resulting in a more potent combustion process within the engine cylinders, thereby generating increased horsepower and torque. However, this is just one aspect of enhancing engine performance. By optimizing the length and diameter of the intake pipe to match the engine's resonance, a greater volume of air is directed towards the cylinders (imagine the engine functioning like a large air pump). This precise tuning enables us to achieve maximum power gains across the entire RPM range.

Why Cummins I6, Not V6

A quick clarification that matters: the 5.9L Cummins in the 1994-2002 Dodge Ram is an inline-six (I6), not a V6. Many listings get this wrong. The Cummins 6BT / ISB is a legendary straight-six diesel — 6 cylinders in a row, not arranged in a V. This intake kit is designed specifically for the I6's turbo inlet configuration and will not fit the 5.9L Magnum V8 gasoline engine found in Ram 1500 models.
