Huey Lewis says it's hip to be square, but is there anything more square than an aging 80s pop star who was square to begin with? Not likely, so when it comes to horsepower and engine protection, take the advice of those in the know and round out your performance cold air intake system with the SynthaFlow Universal Round Air Filter.

Your SynthaFlow filter is crafted from multiple layers of oiled cotton gauze and one crud-catching barrier of unique SynthaFlow material. And, like all Airaid filters, the assembly is supported by a hand-poured urethane frame. The entire structure is sandwiched between layers of rigid epoxy-coated stainless steel mesh for maximum rigidity, even under intense intake pressure. And better yet, Airaid's original oiled design only requires cleaning every 30-50,000 miles and lasts a lifetime.

When it's time to clean your SynthaFlow Round filter, which isn't often, just use the Airaid Air Filter Cleaning kit. After a few steps, your filter is like new, which means you can reuse it oven and over and over. In fact, your SynthaFlow could be your last air filter. Even better, Airaid builds it in the USA and backs your Universal Round Air Filter with a “No Hassle" Lifetime Warranty.
