I have a 2006 grand cherokee and want to make a few mods, but parts seem hard to come by. I have installed a uneek bull bar but want to find a catch can, rear steel bar and fuel prefilter among other things. Can anyone help with where I can get these things and maybe diagrams/pics on installation. I like my Jeep but it seems Jeep and others want to make it as hard as possible to modify these cars. If anyone has any ideas on how to improve performance with spending mega bucks that would be helpful!
