K&N Engineering - Performance Air Filters, Oil Filters, Intake Systems & More

Founded in 1969 in Riverside, California by racers Ken Johnson & Norm McDonald, K&N Engineering revolutionized filtration with the first washable, oiled cotton High‑Flow Air Filter™, designed to boost airflow while keeping engines cleaner—crafted to be reused for up to one million miles.

Over the next five decades, K&N expanded into bolt-on cold-air intakes (1992), Wrench‑Off oil filters (1988), cabin filters, fuel filters, and home A/C filters—now offering over 12,000 SKUs worldwide. Their 400,000 sq ft Riverside HQ, along with facilities in Texas, the UK, Netherlands, and China, houses advanced R&D with airflow benches, chassis dynos, vibration labs, and NASCAR/NHRA-grade pipelines.

K&N products are dyno-validated, ISO-tested, and built for both professional motorsports and daily drivers. Their renowned Million‑Mile/Million‑Mile warranty and global customer support reflect a legacy of trusted performance. Today, K&N continues to lead in innovation—delivering sustainable, high-performance filtration for millions of vehicles on the road.
