Injen Power-Flow Cold Air Intake System Part #PF1959P Customer Reviews

Having bought a used 2007 Nissan Frontier with after market dual exhaust already installed and only getting 16.5 MPG I thought putting the Ingen Power-Flow Cold Air Intake System could improve my MPG. Super easy to install, just need to take your time.

Only a couple negative things. One is that they need to clean the crap out of the inside of the tube and second is, they could have designed the bracket a little better so I didnt have to dremel it to get the Intake to fit right.

I purchased the Injen Power-Flow Cold Air Intake because I wanted just a little kick in performance. When you consider the other manufacturers, Injen products appear to be the best quality intakes you can buy. On to experience, installation is a breeze for me since I can do them practically blind folded because I have done so many on my previous Nissan vehicles. Fit, finish and appearance is top-notch as what I expected. Now for the test drive, I started driving normally for the first week and 50 miles or so. A week later I put it through the test. During acceleration I noticed a lag when pressing the accelerator that wasn't present with the factor setup which is annoying. I had the same experience with my Infiniti M35, Maxima and Altima. There is a pleasant tone when you drive normally and most of the time its basically quiet but when you step hard on the gas, you hear an overly loud noise from the engine bay that I don't particularly care for. To be honest, it just looks good and doesn't really serve a purpose. I lost 1 MPG driving normally which I don't quite understand. With a fuel consuming SUV you need every MPG you can get. Once I get my aftermarket exhaust maybe I will benefit from the Intake.

If I can say anything about this intake it is the fact that it makes my 4.0 sound fantastic under load, and no noticeable drone at cruising speed. As far as power is concerned I was not able to notice a significant increase but all in all it was worth every penny that I spent.

Very Easy installation. Less than an hour for removal of stock intake and installation. I'm not convinced yet of the power increase or any fuel savings. Sound is good though.

I just installed it today. Took it for a drive and heard a loud roar when I put the pedal to the metal. Felt a slight vibration so I might have to check the installation. I probably won't get any better gas mileage because my foot will likely stay on the heavy side.

If I could change anything on the Injen it would be to offer a way to reconect the cold air supply back to the OEM cold air intake. I don't know why they don't offer a way to do this. Don't bother trying to email Injen because they won't answer your email if you ask them if they make or provide such a product. Injen could improve their quality control a bit by cleaning the intake tube. It was full of crap from manufacturing it. I could imagine the problems this would have caused if I had not cleaned it myself.
