About aFe POWER (Advanced FLOW Engineering)
aFe POWER, short for Advanced FLOW Engineering, has been one of the automotive aftermarket's most respected performance brands since its founding in 1999. The company's story starts in a modest 3,200-square-foot facility, where a small team set out to redefine what an automotive air filter could be. From those humble beginnings, the mission was clear: engineer performance solutions that deliver real, measurable results on the dyno and on the road.
What started as an air filter company in a 3,200-square-foot space has grown into one of the most comprehensive performance brands in the industry, operating from over 200,000 square feet of manufacturing, R&D, and warehouse space across Southern California. Today, headquartered in Corona, California, aFe POWER is a household name for enthusiasts looking to squeeze more performance out of their vehicles.
Engineering First, Always
What sets aFe POWER apart is not just the breadth of their offerings, but their engineering-first approach — every product is designed with performance, durability, and fitment in mind, backed by testing and real-world validation. Every aFe POWER product is designed, tested, and manufactured in the USA. That commitment to domestic manufacturing and quality control has earned the brand a loyal following among weekend warriors, professional racers, and daily drivers alike.
aFe POWER has been recognized as an associate sponsor of off-road racing trucks and received the SEMA Global Media Award in 2009 and 2010, as well as the "Editor's Choice Product of the Year" award by Off-Road Business Magazine in 2007.

Whether you drive a gas-powered sports car or a diesel-powered pickup, there's an aFe POWER solution engineered specifically for your application.
Among the brand's most popular categories, aFe POWER exhaust system kits stand out for their mandrel-bent tubing and precision engineering. All tubes of the aFe exhaust systems are mandrel-bent to provide an unrestricted path for exhaust gases. For induction upgrades, aFe POWER air filters represent the product line that started it all — available in multiple filter media types to suit every driving style. Customers can choose from three filter types — the Pro-Guard 7, Pro 5R, and Pro Dry S — each developed for particular driving purposes, with a vehicle-specific design ensuring perfect fit and easy installation, and the Pro-Guard 7 featuring a patented 7-layer design as the brand's most durable offering.
aFe has also expanded well beyond the engine bay. Their aFe POWER coil spring lowering kits are part of the aFe CONTROL suspension lineup. aFe lowering springs are built in the USA and are designed to optimize your vehicle's factory shock absorbers while offering a full 1" drop in ride height, helping increase cornering and overall handling — available for a wide range of vehicles.
