The aFe MagnumFLOW AFE72-90037 replacement air filter is designed for severe-duty environments requiring maximum filtration efficiency and durability. Featuring seven layers of progressively finer mesh cotton gauze and synthetic media, this high-flow conical filter provides superior dust-holding capacity and enhanced protection for your engine. The top and base are constructed from 100% polyurethane, ensuring longevity and resistance to harsh conditions. Its tall, open pleats allow for longer service intervals by trapping more airborne particles before requiring cleaning, making it a cost-effective choice for demanding applications. The integrated urethane bump seal guarantees a tight, leak-free fit throughout the filter*s lifespan, preventing unfiltered air from bypassing the media and safeguarding engine performance.
