Review on Injen Technology SP1240BLK Intake System by Aaron Webb

Gas mileage has improved noticeably and the performance of my 2013 Subaru Outback 2.5i Premium has improved somewhat. Installation was pretty easy, just a few visits to google to sort out some images. When my car is cold the air intake makes an awful rumble and sounds really sick, not in a good way, more of a harsh sound. Once it warms up and I ride for a while, the Injen cold air intake seems to be the most efficient. Wasted on not many extra ooomph.
