Q: What is the difference between the 75-5090 and the 75-5090D?

The 75-5090D (dry) flows 34.22% over stock at 99.61% filtration efficiency and requires no oil.

The S&B 75-5090 cold air intake is built specifically for the 1994-2002 Dodge Ram 2500/3500 5.9L Cummins diesel - not a universal fit. Tested to ISO 5011 standards, the cotton cleanable version (75-5090) delivers 36.63% more airflow than the factory airbox at 99.35% filtration efficiency. The dry extendable option (75-5090D) flows 34.22% better than stock at 99.61% efficiency. Both are CARB Exempt ID D-590-19 and street legal in all 50 states. Select your filter type from the dropdown before ordering - the part number changes between versions.

Buy this if...

You want a measured airflow improvement and stronger throttle response on a 1994-2002 Dodge Ram 5.9L Cummins.
You want a bolt-on, street-legal upgrade with no emissions concerns in any state.
You prefer choosing between an oiled cotton filter or a dry filter based on your service preference.

Do not choose this if...

Your truck is not a 1994-2002 Dodge Ram 2500 or 3500 with the 5.9L Cummins diesel - this is not a universal fit.
You have a body lift, lowering kit, custom hood, or throttle body spacer installed - S&B notes fitment may be affected.

Verify before ordering...

Your year is 1994-2002 and your engine is the 5.9L Cummins diesel (Ram 2500 or 3500).
You have selected cotton cleanable (75-5090) or dry extendable (75-5090D) in the dropdown.

Cotton Cleanable or Dry - Which Version to Pick

Both versions use the same enclosed airbox, large-diameter intake tube, clear lid, and silicone tube seal. The decision is entirely about filter maintenance preference and which performance profile fits your priorities. On this application, the numbers are inverted from what you might expect: the cotton cleanable (75-5090) flows more air (36.63% over stock) while the dry extendable (75-5090D) captures slightly more particulate (99.61% efficiency). Choose cotton if you want maximum airflow and are comfortable with a wash-and-re-oil service routine backed by S&B's Million Mile Warranty. Choose dry if you want the highest filtration efficiency and prefer a no-oil cleaning process - useful in high-dust or off-road conditions. If your fitment and preference match, select the correct part number in the dropdown and this is the right intake to order.

Three Design Details on the 75-5090

S&B built three specific features into this kit for the 1994-2002 5.9L Cummins platform.

Large clear lid with integrated rubber heat seal. The signature polycarbonate lid uses an integrated rubber seal around its perimeter to block engine heat from reaching the filter. You can inspect the filter at a glance without removing the lid.

Large-diameter intake tube. The intake tube is sized to minimize restriction from the filter all the way to the throttle body - a larger cross-section reduces the velocity-based pressure drop that limits airflow in the factory setup.

Silicone tube seal. The connection between the intake tube and the airbox uses a silicone seal that accommodates engine movement and blocks heat ingress at that joint simultaneously. Silicone holds its elasticity and sealing properties in the high-temperature engine bay environment on this platform.

What To Expect On Install

Difficulty: Bolt-on - no cutting, drilling, or specialized tools required
Tools required: 10mm and 13mm wrench/socket, 1/4" wrench/socket, 5/16" nut driver, flat blade screwdriver or panel popper, pliers, Phillips screwdriver
Battery disconnect required: Disconnect both negative battery cables before starting install - engine must be cooled down first
Optional fender liner removal: If the factory threaded stud spins during airbox mounting, fender liner removal is required to secure it from below - panel retainer pins are included to replace any factory pins that break
Post-install step: Affix the included CARB and ID label near the intake kit
Aftermarket fitment note: May not fit with body lift, lowering kit, custom hood, or throttle body spacer installed

Full step-by-step photo instructions for every stage are at the official S&B 75-5090 install guide. Review it before you start - do not work on the vehicle while the engine is hot.

Avoid These Common Mistakes

Ordering without selecting a filter version: 75-5090 (cotton) and 75-5090D (dry) are different products with different filter service requirements. Confirm your selection in the dropdown before adding to cart.
Confusing 1994-2002 and 2003-2007 applications: The 2003-2007 5.9L Cummins uses a different intake - the 75-5094. The 75-5090 fits only the 1994-2002 platform. Ordering the wrong year range results in a return.
Applying oil to the dry filter: The 75-5090D dry filter requires no oil. Adding oil to dry media degrades filtration performance.
Installing with conflicting modifications: A body lift, lowering kit, custom hood, or throttle body spacer may prevent proper fitment. Confirm your build before ordering.
Skipping the CARB label step: The install instructions require affixing the included CARB and ID label near the intake kit after installation. This is required for street-legal compliance confirmation.

Final Check Before You Order

Year confirmed: 1994-2002 Dodge Ram 2500 or 3500
Engine confirmed: 5.9L Cummins diesel
Filter version selected: cotton cleanable (75-5090) or dry extendable (75-5090D)
No body lift, lowering kit, custom hood, or throttle body spacer installed

For a 1994-2002 Dodge Ram 2500/3500 5.9L Cummins owner who wants a street-legal, all-50-states bolt-on intake with 34-37% airflow improvement over stock, the S&B 75-5090 is the correct intake for your truck - confirm your filter type, then proceed with confidence.

Frequently Asked Questions

Click or tap a question below to expand the answer.

Will the S&B 75-5090 fit a 1994-2002 Dodge Ram 2500/3500 5.9L Cummins?

Yes, the S&B 75-5090 and 75-5090D are built specifically for the 1994-2002 Dodge Ram 2500 and Ram 3500 equipped with the 5.9L Cummins diesel. This is not a universal fit - it will not fit the 2003-2007 5.9L Cummins or any 6.7L application. Those year ranges use different S&B part numbers.

What is the difference between the 75-5090 and the 75-5090D?

The only difference is the filter media and the resulting performance tradeoff. The 75-5090 (cotton) flows 36.63% more air than stock at 99.35% filtration efficiency and is washable and reusable, backed by S&B's Million Mile Warranty. The 75-5090D (dry) flows 34.22% over stock but captures more particulate at 99.61% filtration efficiency - no oil is required. On this application the dry version offers higher filtration efficiency; the cotton version offers higher airflow. Both are ISO 5011 tested.

Is the S&B 75-5090 legal in California and all 50 states?

Yes. Both the 75-5090 (cotton) and 75-5090D (dry) carry CARB Exempt ID D-590-19 and are street legal in all 50 US states. The install instructions require affixing the included CARB and ID label near the intake kit after installation.

Does the S&B 75-5090 fit the 2003-2007 5.9L Cummins?

No. The 75-5090 fits only the 1994-2002 Dodge Ram 2500/3500 5.9L Cummins. The 2003-2007 5.9L Cummins uses a different intake - the S&B 75-5094 is the correct part for that application. Ordering the 75-5090 for a 2003-2007 truck will result in a return.

Does the S&B 75-5090 come with everything needed for the install?

Yes, the kit includes the enclosed airbox, air filter (cotton or dry based on your selection), large-diameter intake tube, clear polycarbonate lid, silicone tube seal, all hardware, and panel retainer pins for the optional fender liner step. No additional intake components need to be sourced separately. Full photo instructions are at the S&B 75-5090 install guide.

What replacement filter does the S&B 75-5090 use?

The cotton cleanable version (75-5090) uses replacement filter KF-1035. Both oiled and dry replacement filter options are available on that page. Make sure your replacement filter matches the version you purchased.
