K&N Engine Air Filter KNF-0945 — Extended Life 24,000-Mile Replacement for Ford V8/V10, Direct-Fit OEM Sealing

K&N KNF-0945 is a long-life engine air filter engineered to deliver up to 24,000 miles of reliable filtration and improved airflow for many Ford V8/V10 models.

Designed by K&N, the KNF-0945 Advantage Plus air filter uses a specially treated filter media to balance high-efficiency particle capture with strong airflow. It installs in your factory air box in minutes and is built to meet or exceed OEM fit and performance expectations while providing roughly double the life of many standard disposable filters. This product is supplied as a direct-replacement air element compatible with a broad range of Ford and Lincoln vehicles from the mid-1990s through the late 2010s.

How does this filter protect my engine without hurting airflow?

The KNF-0945 uses a premium synthetic/cellulose blend treated media that traps particulates while preserving air passage. The design prioritizes engine protection up to 99.5% efficiency at capturing damaging debris yet maintains adequate flow for normal and performance driving.

• Specially-treated media for high particle retention
• Engineered pleat structure to balance filtration and airflow
• Meets or exceeds OEM sealing and fit requirements

Will this actually last 24,000 miles and how often should I check it?

K&N rates the KNF-0945 for up to 24,000 miles under typical highway driving conditions, which translates to roughly two years for an average driver. Inspection intervals depend on your driving environment—dusty or off-road conditions call for more frequent checks and earlier replacement than highway use.

• Rated for 24,000 miles of normal use
• Check visually during routine maintenance or when driving in dusty conditions
• Replace sooner if you notice heavy dirt loading or restricted airflow

Is this filter easy to install in my Ford or Lincoln vehicle?

Yes — the KNF-0945 is a drop-in replacement designed to fit your vehicle's factory air box without modification. Most installations take only a few minutes using basic hand tools, and the filter’s sealing surface aligns to the original housing for a secure fit.

• Direct-replacement design for compatible vehicle air boxes
• Simple installation with basic hand tools
• Factory-style sealing to prevent bypassing unfiltered air

Which cars and trucks is this filter compatible with?

The KNF-0945 is compatible with many Ford and Lincoln V8/V10 models from the mid-1990s through the 2010s. Check the model-year list or your vehicle’s part cross-reference to confirm fitment before purchase.

• Fits multiple Ford F-Series, E-Series, Excursion, Expedition and Mustang applications
• Includes compatibility with select Lincoln Navigator, Continental and Blackwood models
• Refer to vehicle list or OEM part cross-reference for exact years and trims

Who is this for? The K&N KNF-0945 is aimed at drivers who want a durable, high-efficiency replacement air filter that reduces replacement frequency compared with standard disposable filters while maintaining OEM-level fit. It’s a practical upgrade for owners of compatible Ford and Lincoln trucks, vans and performance cars who prioritize consistent engine protection, straightforward installation and longer service intervals. If you frequently drive in dusty conditions or desire peak airflow for performance tuning, inspect and replace the element more often to match your demands.
