What K&N Engineering does

K&N Engineering, Inc. is a privately held American manufacturer of automotive and performance filtration products founded in 1969 and headquartered in Corona, California, with a second manufacturing and distribution facility in Grand Prairie, Texas. The company's core product is its high-flow, washable and reusable cotton gauze air filter, built from four to six layers of premium cotton gauze treated with a proprietary tacking agent and sealed in custom urethane frames, designed to increase engine airflow and horsepower versus disposable OE filters while lasting the life of the vehicle. Beyond flagship engine air filters, the portfolio spans cold air intake systems (Classic, NextGen, and NextGen Aluminum lines), oil filters, cabin air filters, marine flame arrestors, powersports filters, heavy-duty commercial filters, residential HVAC filters, and adjacent performance accessories (charge pipes, snorkels, exhaust, throttle control modules, motor oil, fuel additives), supported by sub-brands including AIRAID (DryFlow), SPECTRE, and AEM.

The company's commercial model is a hybrid direct-to-consumer and channel wholesale operation. Direct sales run through the knfilters.com e-commerce storefront with free shipping over $25 in the contiguous US, complemented by an in-house inside sales operation handling phone, email, and technical support for North America and Europe. Wholesale distribution flows through a national retail network anchored by AutoZone, O'Reilly Auto Parts, Advance Auto Parts, Walmart, and Pep Boys, alongside thousands of independent installers, specialty powersports dealers, and regional distributors, with wholly-owned European subsidiaries (K&N Filters (Europe) Limited in the UK and SRM (Europe) BV in the Netherlands) managing international sales and service. Pricing is unit-based across the catalog, with oil filters at $17.99, replacement air filters at $55-$147, cold air intakes at $368-$550, and home HVAC filters sold as lifetime reusable units; warranties range up to a Lifetime Limited Warranty for air filters and a 10-Year/Million-Mile warranty for intake systems, anchoring a value proposition built on durability, dyno-proven performance gains of 5-15%, and lifetime cost-of-ownership versus disposable alternatives.
