aFe Foam Pre-Filter | Universal (28-20004) (SPF28-20004)

The aFe Filter GUARD Foam Pre-Filter is a high-performance accessory designed to enhance the protection of your vehicle’s air intake system. Made from 1/2-inch open cell polyurethane foam, this pre-filter is washable and reusable, providing a durable solution for filtering large particles before they reach the main air filter. Its primary function is to increase dust holding capacity and overall efficiency without restricting airflow, making it ideal for vehicles operated in dusty or dirty environments. The pre-filter can be easily maintained by tapping to remove debris between cleanings and washing with aFe POWER Cleaner during regular service. For added protection, it can also be oiled with aFe’s air filter oil, further improving dust filtration and longevity.

This foam pre-filter is compatible with aFe air filter models 81-10076 and 87-10076. It is suitable for use in various vehicle applications where enhanced filtration is desired, especially in off-road, dusty, or harsh conditions. Designed as a direct replacement or upgrade, it fits seamlessly with the specified filters to provide an extra layer of defense against debris. The product is ideal for off-road enthusiasts, daily drivers, or anyone operating in environments with high levels of airborne dust and dirt, ensuring your main air filter remains cleaner for longer and maintaining optimal engine performance.
