How does this filter affect vehicle performance?

By flowing more air into the engine, the K&N High-Flow filter can help the engine breathe more freely, which can improve throttle response and support horsepower gains in many applications. The media is engineered to balance increased airflow with efficient particle capture so protection isn’t sacrificed for performance.

• Up to 50% increased airflow compared to some stock paper elements
• Multi-layer cotton gauze arrangement traps contaminants while permitting higher volume
• Pre-oiled, ready to install for immediate performance benefit

What maintenance does a washable K&N filter require?

K&N filters are designed to be cleaned and re-oiled instead of replaced frequently. Under normal highway driving the filter typically needs service around every 75,000 miles, though severe or dusty conditions may require earlier attention.

• Clean roughly every 75,000 miles under typical highway use
• Use K&N cleaner and oil for best results and longevity
• Simple remove, wash, dry, re-oil, and reinstall process—no tools beyond the factory airbox access
