I installed the aFe late this afternoon and have the following comments regarding the installation should you decide to do it yourself. The quality of the components is excellent and the fit is almost perfect. For a person who is mechanically inclined, who has basic metric tools, and who can follow directions, the installation is straight-forward. The pictures are good, but they didn't perfectly match my stock Trail Edition. Thus, if you want to do a self install and have no idea what you are doing, there is some room for error. I found that there were some extra plastic brackets holding wiring looms that were not mentioned and electrical tape or zip ties had to be cut to extract the stock components that needed to be replaced with the aFe parts. This was no big deal, but as it wasn't mentioned in the directions, it could prove to be frustrating for certain people. I didn't get a chance to test it out yet, but I hope to over the next several days and I will post my comments.
Cheers,
Greg
