Show original supplier description
The K&N High-Flow 33-2309 is a reusable replacement air filter engineered to increase air flow and enhance engine performance. This design aims to improve horsepower and acceleration. This panel air filter is designed as a direct drop-in replacement for your factory air box, making installation easy and cost-effective for quick performance gains. The filter media is oiled and ready for installation, and K&N suggests it only needs cleaning every 75,000 miles under normal highway driving conditions. By choosing a K&N washable and reusable air filter, users can save money over time compared to purchasing multiple disposable filters, and it contributes to reducing waste in landfills. The product specifications include a re-oiling amount of 1.03 oz, a height of 0.938 inches, and it comes as a single air filter in a box.
