Great looking kit. Easy to install and fits right in. Engine bay looks cleaner and meaner. I have a flashed ECU with VF Tuner and this intake system compliments it with the much needed additional air. Wakes up the 3.5 big time! At WOT there is a very noticeable throaty growl in mid to upper rpm range. At highway speeds the ram air scoop obviously stacks a huge volume of air into the induction, it now pulls hard to redline in every gear. I've noticed it is much easier to gently increase speed and/or quickly accelerate to merge without the truck dropping two gears in the AT to do so, unless you hammer it. Have one tank of gas on it and my mpg's are up over 1+ and that includes stomping on it quite a bit. View window in box allows easy filter viewing and is an awesome feature. Get it!
