AIRAID® 721-478 - SynthaMax® Unique Red Air Filter (4.25" F x 10.813" B x 7.938" T x 7.5" H)

All aftermarket air filter companies make claims for better airflow, but how many of those increases come at the expense of inferior air filtration? AIRAID air filters allow increased airflow while trapping the smallest dirt particles, the size that ordinary cotton-gauze "performance" air filters can't capture. In fact, AIRAID filters have over a 99% efficiency rating. And AIRAID is so confident in the performance of their filters that each one is backed by their "No Hassle" warranty.

The SynthaMax is AIRAID's next generation high-tech air filter. It's 100% synthetic, non-oiled and washable. The inner filter media consists of two distinct layers of specifically designed synthetic materials that have separate performance characteristics. These layers are designed to work together to provide outstanding airflow and exceptionally high filtration. Contaminants are first captured by the outer layer of synthetic needle felt polyester material, designed for wet and dry filtration with high airflow capacity. The inner layer of rayon/polyester captures any remaining contaminants while maintaining high airflow and low restriction. The inner filter media is supported by an inner and outer layer of wire mesh for strength and durability. The SynthaMax filter requires service every 15-30 thousand miles under normal conditions, at which time it should be washed with mild household detergent, rinsed and allowed to dry.

All AIRAID air filters feature a urethane frame, which is much more durable than the rubber used by most aftermarket filter manufacturers. And all panel style filters are made with 304 stainless steel mesh, for exceptional durability. The strength of the stainless steel won't allow the filter to bow in the center, allowing unfiltered air into the engine.

Finally, each AIRAID filter is backed by AIRAID's "No Hassle" warranty. There are no limitations or fine print here. Simply, if you're ever dissatisfied with the materials, workmanship, or performance of this air filter, just send it back... period! You don't have to worry about a proof of purchase or a warranty card. AIRAID filters are warranted for life.
