K&N High-Flow Engine Air Filter for 2015–2023 Ford Mustang & Mustang GT — Model 33-5029, Washable Reusable

The K&N High-Flow Original Lifetime Engine Air Filter 33-5029 is a washable, reusable replacement that increases airflow and supports better engine performance for 2015–2023 Ford Mustang and Mustang GT models.

If you want a direct-fit upgrade for your Ford Mustang that reduces disposable waste while improving airflow, this K&N filter is built to be dropped into the factory airbox and used for the life of the car. Engineered with multiple layers of oiled cotton gauze, it’s designed to let more air reach the engine than a standard paper element, and because it’s serviceable instead of disposable, it can save money over time and cut down on waste.

How does this filter improve my Mustang’s performance?

The K&N design prioritizes airflow without sacrificing filtration. By using layered cotton gauze media and a purposely engineered pleat pattern, it lets a higher volume of air pass through, which can support improved throttle response and potential power gains when compared to restrictive stock paper filters.

• High-flow cotton gauze media increases intake airflow versus typical paper filters
• Multiple filter layers trap contaminants while permitting greater air volume
• Precision fit for 2015–2023 Mustang and Mustang GT for optimal airbox sealing
• Tested on race tracks for durability under demanding conditions

What maintenance does the washable filter require?

K&N filters are pre-oiled and ready to install, and they only need periodic cleaning rather than frequent replacements. Under normal highway driving the suggested service interval is about every 75,000 miles, though dusty or off-road use will require earlier attention.

• Clean approximately every 75,000 miles in regular highway conditions
• Use K&N cleaning and re-oiling kit for best results and longevity
• Simple remove-clean-reoil-reinstall routine — no special tools required
• Reusable design reduces recurring filter purchases and landfill waste

Will this filter fit my specific Mustang model and is installation difficult?

What are the long-term benefits and warranty terms?

Because the filter is washable and designed for lifetime use, it can lower long-term ownership costs and reduce environmental impact compared with disposable filters. K&N backs these filters with a limited 10-year/Million Mile warranty, providing coverage for manufacturing defects within stated limitations.

• Washable, reusable design extends service life beyond multiple disposable filters
