I installed the Injen intake and does it make my truck haul A$$. I do recommend that you wrap your tubes. I've use wraps from designengineering.com or Thermotec.com. Understand that plastic and metal still take some of the engine heat. I have installed a ambient temp meter in my tube to test the difference in degrees from when the day is humid to when it hits 100 plus degress in the summer, to winter. The wrap has lower the air entering the tube up 30-45 degrees lower. Remember that it will vary depending your location.
