Doc's Diesel 7.3L Powerstroke Engine Air Filter DPA5446 — Fits Ford Super Duty F250–F550 2000–2003, Heavy-Duty Silicone Gasket

Doc's Diesel DPA5446 is a heavy-duty replacement engine air filter designed to fit Ford 7.3L Powerstroke Super Duty trucks (F250–F550, 2000–2003), replacing Motorcraft FA1884 and similar part numbers.

If you drive a 7.3L Powerstroke and need a reliable, high-capacity air filter that holds up under dusty, towing, or commercial use, this Doc's Diesel replacement provides durable sealing and deep-pleat filtration engineered for long life. Built with a heavy-duty silicone gasket and pleated filter media, the DPA5446 targets the particles that accelerate engine wear while matching OEM fitment and mounting points for hassle-free installation.

How does the DPA5446 protect my 7.3L Powerstroke engine?

The filter's deep pleated paper increases surface area to capture more dirt and debris before contaminants reach the turbo and cylinders. A robust silicone gasket maintains a positive seal even when the truck is exposed to vibration and rough terrain, reducing bypass risk.

• High-capacity pleated media traps fine dust and larger particulates.
• Heavy-duty silicone gasket resists compression set and leaks.
• Designed to align with factory intake housing for consistent airflow.

How durable and tested is this Doc's Diesel filter?

This DPA5446 model has been third-party tested for dust-holding capacity, showing strong performance under controlled lab conditions. The construction prioritizes longevity under heavy loads and frequent exposure to road dust, making it suitable for commercial and recreational towing demands.

• Third-party tested dust holding capacity: 344.2 g (99.25% efficiency in test conditions).
• Rugged gasket material reduces risk of intake leaks over time.
• Engineered pleat depth increases service intervals compared to thin-media filters.

When should I change the DPA5446 filter in my Powerstroke?

Replace the air filter according to your vehicle manufacturer’s recommendations and warranty requirements, but adjust frequency based on driving conditions. In normal driving, filters are commonly replaced between 5,000 and 10,000 miles; in very dusty or off-road conditions replace more often.

• Recommended interval: every 5,000–10,000 miles for typical use.
• Maximum suggested interval: 12,000 miles unless the manufacturer specifies otherwise.
• Inspect during oil changes or heavy-use seasons for early replacement if clogged.
