Designed as a direct-fit upgrade for select 2023–2026 Honda models, this K&N filter swaps into the factory airbox in minutes and uses multi-layer cotton media to increase airflow while capturing contaminants.

It’s engineered and manufactured in the USA and tested under demanding conditions to balance filtration and flow for street-driven vehicles.

How does this filter affect engine breathing and performance?

By using a specially designed cotton gauze media arranged in multiple layers, the filter reduces restriction and allows more air to reach the intake. More airflow can translate to improved throttle response and maintaining peak performance under load, while still trapping dust and particulates.

• Multi-layer cotton media for increased airflow
• Engineered to fit the factory airbox for optimized intake flow
• Designed to improve throttle response and maintain consistent performance

What maintenance does the K&N 33-5145 require and how often?

The filter arrives pre-oiled and ready for installation; cleaning is needed far less often than disposable filters. Under typical highway driving, K&N recommends inspecting and cleaning the filter approximately every 75,000 miles, but conditions like heavy dust or off-road use may require earlier service.

• Clean roughly every 75,000 miles in normal highway conditions
