Doc's Diesel Engine Air Filter DPA6109

Doc's Diesel DPA6109 is a heavy-duty replacement engine air filter designed to fit Ford 6.7L Powerstroke F250–F550 (2011–2016), providing high dust-holding capacity and a durable silicone seal.

This replacement air filter is engineered for diesel trucks that see hard use: deep-pleated filter media captures contaminants while a reinforced silicone gasket preserves a tight seal in dusty or off-road conditions. It meets common OEM interchange references (including Motorcraft FA1902) and has been third-party tested for filtration performance and dust capacity to help maintain engine efficiency and longevity when changed on a proper schedule.

How does this filter protect a 6.7L Powerstroke under heavy duty conditions?

The DPA6109 uses densely pleated filter paper to trap fine dust, dirt, and debris before they reach the intake, reducing abrasive wear on engine components. A robust silicone gasket resists compression set and keeps contaminants from bypassing the media during vibration or rough terrain.

• Deep-pleat media increases surface area for contaminant capture.
• Heavy-duty silicone gasket maintains a tight seal under vibration.
• Designed to withstand dusty or off-road environments common to diesel use.

Is this an exact fit for Ford F250, F350, F450, F550 2011–2016?

Yes — the DPA6109 is specifically produced to fit Ford 6.7L Powerstroke models from 2011 through 2016. It aligns with factory dimensions and sealing surfaces to install quickly without modification.

• Direct compatibility with Ford 6.7L Powerstroke F250–F550 (2011–2016).

Which OEM and aftermarket part numbers does this replace, and why does that matter?

Doc's Diesel DPA6109 cross-references several established part numbers so you can use it as a drop-in alternative when filling service or maintenance needs. Using a compatible replacement simplifies sourcing and ensures you maintain recommended filtration performance.

• Interchange references: Motorcraft FA1902, Wix 49902, Baldwin PA4433, Purolator TA36109.
• Makes it easier to match service records and warranty schedules.
• Provides consistent fit and filtration where those part numbers were originally specified.

How often should I replace the DPA6109 for reliable performance?

Replacement intervals depend on driving conditions and manufacturer guidance. Doc's Diesel recommends routine replacement between 5,000 and 10,000 miles for typical conditions, with 12,000 miles as an upper limit, but always follow your vehicle manufacturer’s warranty and service recommendations first.

• General guideline: every 5,000–10,000 miles for regular dusty use.
• Up to 12,000 miles maximum under lighter, cleaner driving conditions.
• Inspect more frequently in very dusty or off-road environments.

Who is this for? The DPA6109 is intended for Ford 6.7L Powerstroke owners who need a rugged, affordable replacement air filter that mirrors OEM fit and performance. Professional technicians, fleet managers, and owners of work trucks that face dusty job sites or frequent towing will value the combination of high dust-holding capacity and a durable silicone seal. If you require a direct-fit filter that cross-references Motorcraft FA1902 and other common part numbers while offering third-party-tested dust retention, this Doc's Diesel unit is a practical choice for maintaining engine protection between scheduled services.
