K&N High-Flow Engine Air Filter 33-5000 — Ford/Lincoln Fit, Washable Lifetime Performance

The K&N High-Flow Original Lifetime Engine Air Filter 33-5000 is a washable, reusable replacement filter designed to increase airflow and improve engine performance while lasting for the life of your vehicle.

This premium K&N filter replaces the factory paper element in many Ford and Lincoln models (Edge, Fusion, GT, Continental, MKX, MKZ, Nautilus) and is engineered to allow higher airflow without sacrificing filtration. Built with multiple layers of oiled cotton gauze, it’s pretreated and ready to drop into your factory air box, offering a straightforward upgrade for drivers who want better throttle response and long-term value.

How does this filter boost performance?

By optimizing airflow through its layered cotton-gauze media, the K&N 33-5000 reduces intake restriction and can help the engine breathe more freely, which often translates to improved throttle response and potential horsepower gains. Results vary by vehicle and conditions.

• Multi-layer cotton gauze increases air transfer while still trapping contaminants
• Engineered media designed and tested on race tracks for consistent flow
• Pre-oiled for immediate performance after installation

What maintenance does the washable filter require?

This K&N element is designed to be cleaned and re-oiled rather than replaced; under typical highway driving it only needs cleaning roughly every 75,000 miles. Cleaning intervals depend on driving environment—dusty or off-road use will require more frequent attention.

• Clean approximately every 75,000 miles in normal highway conditions
• Simple clean-and-reoil procedure—no special tools required
• Reusable design reduces waste from disposable filters

Is installation difficult for a home mechanic?

Installation is intentionally straightforward: the filter fits into the stock air box and uses the same mounting points as the original element. Most installations take only a few minutes with basic tools and no modifications to the vehicle.

• Direct-fit replacement for listed Ford and Lincoln models
• Pre-oiled and ready to install out of the box
• No cutting or aftermarket hardware required

What warranty and environmental benefits come with this filter?

K&N backs this filter with a limited 10-year/million-mile warranty, reflecting its long service life and manufacturing confidence. Because the filter is washable and reusable, it helps reduce the number of disposable filters sent to landfills over the life of the vehicle.

• Limited lifetime warranty for stock replacement K&N filters (limitations apply)
• Reduces landfill waste by replacing many disposable filters
• Manufactured in the USA using durable construction materials
