In the wild world of aftermarket performance parts, it's easy to get confused — especially with seemingly similar products from the same brand. One common question we hear is, “What's the difference between the AirAid SynthaFlow and SynthaMax Air Filters?” To help you along in your air filter decision process, we've wrangled together the key differences—and some similarities —between the two products. Whether you choose a SynthaFlow or SynthaMax air filter, all AirAid products are top-of-the-line accessories, hand-built from the finest materials and backed by a Lifetime Warranty. Whichever air filter you choose depends solely on your personal taste and vehicle's performance needs.
Every SynthaFlow Oiled Air Filter is composed of multiple layers of cotton gauze. Those layers, coupled with unique synthetic materials, provide superior filtration for your air intake. This filtration allows for maximum airflow through your engine, resulting in improved torque, horsepower and even fuel economy. With its oiled surface, a SynthaFlow air filter boasts the optimal combination of airflow and filtration. Better yet, you only need to clean your filter every 30-50k miles — simply wash it with AirAid Filter Cleaner and allow it to dry. It's beneficial to have a spare filter on hand during the washing and drying process.
On the other hand, the SynthaMax Air Filter sports a non-oiled surface and is composed of 100% synthetic materials. These materials increase filtration and airflow by upwards of 99% for heightened engine efficiency. Since SynthaMax filters aren't oiled, they need to be cleaned more regularly than their SynthaFlow counterparts, but you can easily wash them with regular household detergents. So, while SynthaMax air filters aren’t quite as powerful, they're much more manageable.
The ultimate air filter decision lies on whether you crave top-notch performance with slightly more maintenance effort, or increased performance with an easier maintenance routine. All AirAid filters are made in the USA, backed with a Lifetime Warranty, are washable and reusable and come with Free Shipping and a 1-Year, Lower Price Guarantee from AT.
