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.

At first glance, the SynthaFlow filter would appear to be just another aftermarket cotton-gauze air filter, but it's much more advanced. The SynthaFlow is a cotton-gauze and synthetic blend that outperforms plain cotton-gauze in clean air testing. The SynthaFlow features "five layer" filtration, with 4 layers of cotton-gauze supplemented by "the last layer of defense", a layer of synthetic media that produces the cleanest air of any washable filter. The filtering media is held together by epoxy coated aluminum wire mesh, specially designed to provide the optimum balance between maximum airflow and peak filtration. The SynthaFlow filter only requires servicing every 30-50 thousand miles under normal conditions, at which time it should be washed and re-oiled.

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.

AIRAID® was founded in 1997 when they began developing and manufacturing air intake systems for light trucks and SUVs, utilizing the cotton-gauze filter technology that was available at the time. These systems increased airflow and performance while being easy to install, and sold so well that the company soon realized that another source of filters was necessary. They believed they could produce a better quality filter using new technology and state-of-the-art materials, and so in 2002 the AIRAID Filter Company was formed. Today AIRAID is the recognized leader in air management technology. Extensive research and development has allowed AIRAID to come to market first with high quality products that improve drivability and performance.
