Wrangler TJ/LJ Cabin Filter adapter

Install a cabin filter in your late model Jeep Wrangler TJ! These vehicles never included one from the factory and instead just blow exterior air directly into the cabin. If you have ever been on a dusty road in your Jeep, you know how bad this is. Not only does it get your interior dirty and make you breathe the dust, but it can clog up your heater core. This adapter allows you to install a proper cabin filter over the under-cowl interior air intake to reduce dust, pollen and other contaminants from making it into your cabin.

Installation is easy and requires only a screwdriver to remove the cowl and install the adapter. After that, replacing the filter is as easy as lifting out the old one and putting in a new one.

This takes a standard cabin filter which is used on later Jeep Wrangler models, Jeep/Mopar part number 55111302AA. The Fram FDC11777 will fit, but any other brand for a 2011-2013 Jeep Wrangler will work as well. Replacement filters can be had for about $5 each.

This updated version holds the filter more tightly and further down inside the duct for even more clearance between it and the cowl cover.

Notes:

• This is intended to fit 2002-2006 Wrangler/TJ/LJ models. It may fit some earlier models as well (2000-2001 should fit with some trimming of the factory plastic cowl duct).
• Be sure to confirm that your Jeep has an intake under the front cowl like the one pictured before ordering. Message me for details first if you need help!
• You should be able to re-use the factory screws from the intake boot, but due to differences in Jeep manufacturing tolerances, you may need longer hardware (not included)
• This is a retrofit and as such it does not form a perfect seal and will not prevent all dust and contaminants from reaching the cabin
• This is a 3D-printed part using ASA (or ABS). Color and finish may vary. Heat tolerance of 200F is typical.
