The aFe high-performance, high-flow OE air filter replaces the restrictive factory paper filter and lets your engine breathe better. Paper filters do a good job in keeping dirt out but can be clogged easily and need to be replaced frequently. Same with the foam filters being sold nationwide. This is a washable and reusable, cotton gauze filter with Pro-Dry S, which allows more air flow.

With the aFe PT Cruiser OE Replacement Filter with Pro-Dry S, the engine can breathe a lot better. These filters are built to let the engine breathe better even as the filter gets dirty. The multiple layers of cotton gauze are sandwiched between two layers of epoxy-coated aluminum screen and pleated like a lamp shade. One or two layers would allow dirt and dust particles to pass through, so aFe has stacked multiple layers with progressively tighter mesh to catch progressively smaller and smaller particles—as small as 2 microns in size. The aluminum screen holds the layers in place and protects the cotton gauze.

The aFe PT Cruiser OE Replacement Filters with Pro-Dry S are designed differently than other cotton gauze filters. They are designed to have the tallest pleats that the factory air box will allow. Taller pleats mean more filter material to hold the dirt, and the pleats can be spaced out more to let more air through. Rounded design allows the air to flow more efficiently around the tops of the pleats. The pleats aren't tightly pinched, which allows air flow through the tops and bottoms of the pleats.

The aFe PT Cruiser OE Replacement Filter with Pro-Dry S uses 100% engineering-grade polyurethane, which is more flexible and will seal better in today's plastic and fiberglass factory air boxes. To make sure these filters stand up over the life of your vehicle, they have been designed with urethane on all four sides of the filter, not just on the open ends. So make the right decision for your PT Cruiser and choose aFe.
