2003–2007 Dodge Ram 2500/3500 5.9L Cummins Cold Air Intake Kit
A more aggressive intake note under acceleration and potentially sharper throttle response make this Flashark cold air intake kit a focused choice for 2003–2007 Dodge Ram 2500 and Ram 3500 trucks with the 5.9L Cummins L6 diesel engine. The heat-shielded design pairs aluminum intake piping with a washable, reusable red filter for owners who want a serviceable performance intake in place of the factory assembly.

Key Features
- Heat-shielded intake layout: The kit uses a heat shield around the red cone filter for a clean, performance-focused underhood layout.
- Aluminum intake piping: The intake path uses aluminum piping with a polished-pipe finish for the kit’s underhood hardware.
- Washable cotton filter: The reusable dual-layer pleated cotton filter can be cleaned and re-oiled instead of being discarded after routine service.
- Long service interval: Under suitable driving conditions, the reusable filter may only need cleaning about every 100,000 miles; inspect it sooner when dust loads the pleats.
- Factory-sensor compatibility: The system is designed to work with factory sensors and the original engine-management system on compatible trucks.
- Power potential: Depending on engine condition, calibration, supporting hardware, and installation, the kit can add up to 14 hp and 13 lb-ft.
- Intake sound and response: The intake is engineered to deliver a more aggressive sound under acceleration and may sharpen throttle response.
- Bolt-on hardware and instructions: The kit includes installation hardware and instructions for 2003–2007 Ram 2500/3500 trucks with the 5.9L Cummins engine.
Who This Kit Is For
This kit is for 2003–2007 Dodge Ram 2500 and 3500 owners with the 5.9L Cummins L6 diesel who want a reusable-filter intake kit. It suits owners looking for a polished aluminum intake path, routine filter serviceability, and a more pronounced intake sound during acceleration.
- Choose it if your truck is a 2003–2007 Ram 2500 or 3500 with the 5.9L Cummins diesel.
- Choose it if you prefer servicing a washable cotton filter rather than replacing a disposable filter.
- Choose it if you understand that intake-only power and fuel-economy results vary by vehicle and setup.
- Do not choose it for a Ram 1500 or a 6.7L Cummins application.

Check Before Ordering
- Vehicle match: Verify 2003–2007, Ram 2500 or Ram 3500, and the 5.9L Cummins L6 diesel engine. A 2007 truck can have a 5.9L or 6.7L Cummins, so confirm the engine before ordering.
- Factory configuration: Confirm that your truck retains the factory sensor and intake configuration required by this kit.
- Filter service: Inspect the filter regularly. Clean it when the pleats begin to collect dirt; dusty farm, construction, gravel-road, or trail use can require more frequent service than paved-road use.
- Oil application: Let the cotton filter dry fully before re-oiling and use only a light, even amount of filter oil. Over-oiling can contaminate nearby intake sensors.
- Water exposure: Avoid deep-water crossings. Water ingestion can cause hydrolock and severe engine damage.
- Emissions rules: Check your local emissions requirements before purchase, especially in California and other CARB-adopting states.

2003–2007 Ram 2500/3500 5.9L Cummins Cold Air Intake Kit FAQs
Q1: Is this cold air intake legal in my state?
A1: Not legal for sale or use in California (and other CARB-adopting states). Check the emissions requirements that apply where you register and operate the truck before ordering.
Q2: Will this fit my 2003–2007 Dodge Ram 2500 or 3500?
A2: It fits 2003–2007 Dodge Ram 2500 and Ram 3500 trucks with the 5.9L Cummins L6 diesel engine. Confirm the year, model, engine, and factory intake configuration before ordering; compatible 2WD and 4WD configurations still need to match the correct vehicle setup.
Q3: Will it fit a Ram 1500 or a 2007 truck with the 6.7L Cummins?
A3: No. This kit is not made for the Ram 1500 or for the 6.7L Cummins. The 2007 model year can include either 5.9L or 6.7L engines, so verify the engine from the vehicle information before purchase.
Q4: How much horsepower will this add?
A4: This kit can add up to 14 hp and 13 lb-ft, while a typical cold air intake range is about 5–15 hp. Actual results depend on engine condition, turbo condition, calibration, exhaust flow, elevation, ambient temperature, installation, and supporting hardware.
Q5: Will a cold air intake improve my MPG?
A5: MPG is dominated by driving habits; an intake alone cannot guarantee a measurable gain. Expect the main benefit as throttle response and intake tone rather than fuel economy.
Q6: Will this void my warranty?
A6: Under the Magnuson-Moss Warranty Act, an aftermarket part cannot void your factory warranty unless it is proven to have caused the failure. This kit is designed as a bolt-on intake that works with factory sensors and engine-management components on compatible trucks.
Q7: Do I need a tune after installing?
A7: A tune is not normally required for a straightforward installation on a compatible stock truck. A custom tune may be used for trucks with other modifications, such as larger injectors, an upgraded turbo, or a performance exhaust.
Q8: Is the included air filter washable and reusable?
A8: Yes. The kit uses a washable, reusable dual-layer pleated cotton filter. Inspect it regularly and clean it when dirt accumulation begins to restrict the pleats; dusty use requires more frequent service.
Q9: How do I clean and re-oil the filter?
A9: Use a cleaner intended for reusable cotton filters, rinse and let the filter dry completely, then apply a light, even amount of filter oil. Avoid over-oiling because excess oil can contaminate nearby intake sensors.
Q10: What does it sound like and can it help throttle response?
A10: The kit is intended to provide a deeper, more aggressive intake sound under acceleration, while highway cruising is described as comparatively controlled. It may help throttle response, but the change depends on the truck’s condition and supporting modifications.
Q11: What is included with this intake kit?
A11: The kit includes the aluminum intake pipe, red performance air filter, heat shield, couplers, clamps, mounting hardware, and installation instructions. Review the box list and retain the factory components required by your vehicle before starting installation.
Q12: Is this intake suitable for towing?
A12: It can be used on daily-driven and towing trucks when correctly installed and maintained. It does not increase the truck’s factory tow rating; continue monitoring exhaust-gas temperature, transmission temperature, coolant temperature, boost, and filter condition during heavy towing.
