DVPARTS 4in Blue Oiled Cold Air Intake Filter — 4" Reusable Washable Replacement for Rudy's and Powerstroke Trucks

The DVPARTS 4" blue oiled cold air intake filter (DP0235) is a washable, reusable replacement that fits Rudy's 4" intakes and other 4" ID systems for Powerstroke diesel Super Duty trucks.

This replacement element gives you a direct-fit option for 4" inlet cold air intakes used on many Ford Super Duty Powerstroke diesels from 1999–2021. Built to accept oil for improved dust capture and designed to be cleaned and reused, the DP0235 covers multiple DVPARTS part cross-numbers and fits applications where a 4" internal diameter filter is required.

Will this filter physically fit my intake system?

Yes — the DP0235 is engineered to mate with any intake that accepts a 4" inner-diameter filter. It is supplied in a 4" inlet size so it slides into place without trimming when matched to compatible housings. Always confirm the intake calls for a 4" ID filter before ordering.

• Specification: 4" inlet diameter for direct compatibility
• Fits Rudy's 4" intake systems out of the box
• Also works with other brands that use a 4" internal filter
• Cross-reference part numbers: DP0235, DP0091, DP0173, DP0107, DP0106, DP0321, DP0286, DP0190

How do I maintain and service the washable oiled filter?

Cleaning and re-oiling is straightforward: remove the filter, wash gently with a suitable cleaner, allow to dry, then apply filter oil evenly before reinstalling. Regular inspection helps maintain airflow and filtration performance. Follow manufacturer-recommended cleaning intervals based on driving conditions—more frequent for dusty or off-road use.

• Wash using a dedicated air filter cleaner and rinse thoroughly
• Let the filter dry completely before oiling
• Apply filter oil sparingly and evenly to capture particulates
• Inspect for tears or damage; replace if the media is compromised

What distinguishes this DVPARTS replacement from disposable elements?

Because the DP0235 is washable and oiled, it’s designed for multiple cleaning cycles rather than one-time discard. That reduces recurring filter purchases while preserving filtration performance when maintained correctly. The oiled media traps fine particles better than many dry disposable filters when properly serviced.

• Reusable media lowers long-term maintenance cost
• Oiled construction helps capture finer dust and debris
• Durable build intended for repeated cleaning cycles
• Sold as a single replacement element for 4" intakes

Who is this for: The DVPARTS DP0235 filter is aimed at owners of Ford Super Duty trucks and other vehicles that use a 4" intake element—especially drivers who prefer reusable, oiled filters for better particle capture and reduced replacement frequency. It’s a practical choice for off-roaders, fleet vehicles, and anyone running Rudy's 4" intake systems or aftermarket 4" ID intakes looking for a cost-effective, maintainable replacement part.
