Be the first to review part 33-2039
I just installed the 33-2039 original replacement filter to my Lebaron and wow I feel the response of the turbocharger more quickly and increase 1psi of boost¡¡¡¡ at wot, from 14 psi to 15 psi of boost.  I don`t know that with these small change my car runs a little better, and the fuel consuption was less than the stock air of fun¡¡¡¡ =)

I have a 2005 Dodge Ram 4x4 5.7L Hemi Daytona Truck (the orange one). I've added in two [brand] with the stock air cleaner/housing. The sound is great just from the flows, but when I open it up at about 4800-6000 RPM it just sounded like air moving through an air tunnel with no muscle behind it. I took out the stock cleaner/housing and added in the 77-seriers and a night and day difference. When I open it up (flooring it) I get a sound that you normally only hear on a 1/4 track, lol. If your looking for a deep very mean and very aggressive sound, then you want a 1-chamber flow and this 77-seriers. Not to mention that it only took me about 10-15 mins to change it out. Very easy to do.
