When it comes to unlocking your engine's explosive energy, timing is everything. Injen's Power-Flow Cold Air Intake is engineered to deliver a blast of oxygen at the perfect moment for blazing combustion and gut-wrenching power output.
While basic intakes merely force air down an engine's gullet, the Injen Power-Flow puts your motor on a steady diet of colder, richer oxygen. The process starts with the high-flow air filter's integrated Air Inducer, Air Stabilizer and Velocity Stack. Air is drawn in, smoothed out and pressurized.
From there, the oxygen flows through the Mega Ram-tuned pipe, where it gets released to the mass air flow senor at calculated intervals. Each kit goes through a rigorous dyno-testing process and fine-tuned to unleash ferocious performance across the RPM spectrum. Some vehicles come with a Power Box heat shield if needed.
Your Injen Power-Flow bolts on without any drilling for a simple at-home installation. Lifetime Warranty on tube and filter.
Thanks to the Magnuson Moss Warranty Act: US Code – Title 15, Chapter 50, Sections 2301-2312, your vehicle’s factory warranty is protected by law when you add aftermarket parts. Details

The outer end of the air box does not seal to the factory fender hole allowing hot air to get around it. Also, there are air intake holes on the top and front of the box that allow hot/warm air from engine heat to get in from under the hood. The fit was very hard on my Silverado. All the pieces were so tight that I had to force the pipe over very hard to get it to fit on the intake manifold. Very little space for engine tork/ rock. I have been talking to Injen with no resolution as of yet.

I chose the shorter Injen intake system for my 2010 Camaro with an average rated 13 hp increase instead of the longer one with 16 hp increase for 2 reasons: 1. Easier installation. It only took me one hour and I did not have to remove my wheel. 2. Less likely water infiltration. My roads sometimes get flooded requiring me to drive through 1.5 feet of water and I hear you do not want to get this thing wet. I can definately tell a difference in acceleration. However, my engine is 25% louder now with strong acceleration, which does not bother me. The installation instructions were very clear and easy to follow. I am very satisfied with my purchase. Tip: Make sure you have a wide variety of allen wrench heads at your disposal before attempting installation.

I have had the Injen Power Flow Cold Air Intake for about a month now and as far as I can tell there is no performance increase in mileage at all. The sound of it is great and it seems to have more torque and horsepower on the lower end. I say "seems" as the sound of the system may give the perception that torque and horsepower has increased. Installation was average at best as the instructions need to be updated. Workmanship and material appear to be topnotch. Recommendation: save your money.

The install was smooth. Made a +2mpg increase when not in the throttle, when on the throttle the response is impressive, and to top it all off the intake sound is AMAZING. Injen is always first in my mind.

The install was great until the crank case vent hose, that was a drag. I still don't have it right. Tomorrow. I will say this, WOW!!! Like It improved my throttle response about 20%. The sound is mean. It looks beautiful. the whole unit weights about 2/3's less than stock. I wish the vent hose was a better design.
