CARMOCAR Air Filter for Ford 6.0L Power Stroke V8 FA1778 Replacement — 2003–2007 Super Duty Fit, Folded Paper Media

CARMOCAR FA1778 is a direct-fit engine air filter designed to replace OEM FA1778 and compatible part numbers for Ford 6.0L Power Stroke V8 engines (2003–2007) including F250–F550 and 2003–2005 Excursion.

Keep dirt, dust, and engine-damaging particles out of your turbo diesel with an aftermarket filter engineered to match the original equipment fit. This CARMOCAR replacement uses a folded cellulose-mixed paper element inside a rigid plastic frame to sustain airflow while trapping contaminants. It’s intended as a straightforward swap for owners and technicians who need a reliable, budget-friendly air intake filter for older Super Duty trucks.

What materials and filtration performance does it use?

This filter uses folded cellulose-mixed paper media supported by a rigid plastic frame to balance filtration efficiency and airflow. The pleated paper captures particles effectively while the frame maintains shape under engine bay heat and vibration.

• Folded cellulose-mixed paper filter element for particle capture and airflow management.
• Rigid plastic frame resists warping and helps maintain a secure seal in the airbox.
• Designed to capture a high percentage of common engine contaminants while allowing adequate intake volume.

How does installing this filter affect engine performance and longevity?

Replacing a clogged or worn air filter restores proper airflow to the engine and keeps abrasive particles out of sensitive components. While not a performance upgrade part, a clean, correctly sized filter supports steady combustion, turbo response, and long-term component protection.

• Helps protect the turbocharger, mass airflow sensor, and cylinders from contaminants.
• Improves air flow relative to a dirty or blocked filter, helping maintain fuel efficiency and throttle response.
• Captures up to approximately 98.5% of common airborne particulates in typical conditions.

What should I know about maintenance and warranty?

This CARMOCAR air filter is intended as a durable, long-lasting replacement part for routine service intervals. Inspect and replace according to your vehicle’s maintenance schedule or sooner in heavy-dust environments. CARMOCAR provides a one-year customer service period for this product.

• Replace during scheduled air filter service or when visibly dirty—more often in dusty conditions.
• One-year customer service/support from CARMOCAR for product-related issues.
• Always verify fit by comparing the part and reference pictures or OEM numbers before purchase.

Who is this for: The CARMOCAR FA1778 is aimed at truck owners, independent mechanics, and fleet managers who maintain Ford Super Duty trucks with the 6.0L Power Stroke engine and need a cost-effective, OEM-compatible air filter.
