Just like a three-piece suit, replacement parts for your vehicle aren't always what you could call ‘direct-fit.' Pants need to be hemmed, jackets need to be let out and performance car parts need to be modified. But, just like one of those rare off-the-rack finds at the Big & Tall, the Airaid SynthaMax Air Filter is a perfect fit—right outta the box.

Crafted from two layers of non-oiled, 100% synthetic fiber, Airaid SynthaMax filters are supported by a urethane frame and 304 stainless steel mesh. On the outside, needlefelt polyester delivers the first stage of filtration and high-airflow. Then, rayon and polyester layers capture any pollutants that sneak through—giving you maximum airflow and ultimate protection against piston-pummeling particles.

The secret behind SynthaMax is ease of use and longevity. It requires no oil, so you just clean it with regular household detergent, dry and reinstall. The material is completely reusable, meaning your SynthaMax could be the last air filter you buy. And best yet, Airaid makes it right here in the USA and backs your Air Filter with a “No Hassle" Lifetime Warranty.

Goo quality but very tight fit in stock airbox

Ease of Installation

If you are looking for a filter to replace stock that you will not have to oil or ever replace this is a good deal. Fits the stock air box but is just a little taller so getting the cover back on the box is a little harder. I read other review where people thought it help with response and maybe a little mpg. I did not experience any of that since installing.

Easy to install and fits well. No discernable power difference or mpg gain nor was one anticipated. I bought it to save money over the OEM filters and anticipate that being the case.
