Cold Air Intakes
Custom-engineered tubes deliver better airflow than you get with a stock intake. More air means better performance.
Using cotton gauze instead of typical folded paper, our filters increase airflow while providing excellent engine protection.
Cabin Air Filters
Helps capture most mold, mildew, fungus, spores, bacteria, germs, pollen and allergens, and helps to rid the air of unpleasant odors.
K&N oil filters use a high flow filter media that allows for high flow rates while providing outstanding engine protection.
From custom air filters to fuel pumps and carb accessories, the K&N Speed Shop has been assembled to help your vehicle run at peak performance.
K&N is the home of the original red oiled air filter. In the early 1960s, two motorcycle racers, Ken Johnson and Norm McDonald (K&N), developed a ground-breaking new idea for an oiled air filter. Five decades later, K&N® is still innovating industry-leading filtration technology, and offers outstanding protection for everything from top-fuel dragsters to commuter vehicles across the globe.
