K&N Air Filters

K&N Air Filters

K&N air filters have set the benchmark for performance filtration for over 50 years. Built with a multi-layered, oiled cotton design, K&N filters offer superior airflow without compromising engine protection—delivering more power, better throttle response, and long-term value.

Whether you're on the street, the track, or off-road, a K&N air filter is one of the smartest upgrades you can make.

Why Choose a K&N Air Filter?

K&N filters are engineered to be more than just a direct replacement—they’re designed to improve performance, extend service intervals, and reduce waste.

• Increased Horsepower & Acceleration – High-flow design improves intake efficiency.

Built for Performance, Backed by Science

K&N filters use a deep-pleated cotton media with a proprietary oil treatment to trap dirt and debris while allowing increased airflow. The result? More efficient combustion, a cleaner engine, and potential gains in power and fuel economy.

Each filter is tested to meet ISO 5011 standards for filtration and airflow.

Made to Last the Life of Your Vehicle

While paper filters often need replacing every 10,000–15,000 km, a K&N air filter can go up to 80,000–100,000 km between cleanings under normal conditions—and can be used for up to a million kilometres with proper maintenance.

Just clean, re-oil, and re-install.
