AutoFrontiers is a small, family-owned automotive parts business based in the southeastern United States. Our goal is simple: build useful, reliable parts that solve real problems for owners of older vehicles. Many models left the factory without a cabin air filter. Our retrofit kits are designed to help reduce dust, pollen, leaves, and road debris entering the HVAC system while helping protect the blower motor and A/C evaporator.

We believe in doing things the right way. Our products are designed, assembled, and shipped domestically. From product design to packaging and shipping, we focus on quality, fitment, and dependable customer service. Whether you are restoring an older vehicle, improving your daily driver, or keeping trail dust out of your cabin, you should find our products helpful and dependable.
