"I bought this intake because I had heard that it offered some boost in performance because of the increased flow to the turbo. Did it ever! I've found that I now have to monitor how fast I'm going because the car will quickly climb to 80 mph without even trying.
I was initially concerned by the design, since it's more of a short ram intake than it is a cold air intake. However, with the provided air diverter, does a great job. And I love the sound it makes. Good buy!" —Deon L from Hoboken, NJ bought an Injen SP Series Cold Air Intake for a 2011 Kia Optima.
