      No matter which brand aftermarket CAI kit you went with, it certainly delivered seat-of-your-pants performance gains right out of the box. But, lately you may be noticing that the punch in your pedal is not what it once was. So instead of replacing that air filter with the same here-today-gone-tomorrow performance, go with the proven power of the high-performance SynthaFlow Cold Air Intake Replacement 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 304 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 finally time to clean your SynthaFlow Round filter, just use an Airaid Air Filter Cleaning kit offered separately. Your filter comes out like new, which means you can reuse it oven and over. Meaning your SynthaFlow could be your last air filter. Plus, Airaid builds it in the USA and backs your Air Filter with a “No Hassle" Lifetime Warranty.

      Since buying my first airaid CAI I have always used there filters. I have installed them on every vehicle I have owned. Fit and finish is great and performance is as advertised. I hope in the future thew will offer a CAI system for a 2015 Kia Forte5 SX turbo. Great product.
