Well I pulled the trigger and ordered the Magnuson SC for my 2012 JK. They said two weeks to get all the part in and then they will start the install. I plan on having them Dyno the Jeep before and after to document the performance gain. Having Poison Spyder front bumper and alumimun wheel flares put on this weekend. The installer said the flares where a pain in the butt to install (don't know what that really means).
