I bought an Injen CAI before for my 2013 Focus and it was fantastic. This Power-Flow that I just bought for my 2014 Mustang is a bit of a let down though. Quality is not as good and looks/feels a little cheap. I do feel a little more low end power but its quiter then expected, but rev it above 4500 and it finally comes alive. Its ok and I am hoping with my throttle body upgrade I get some better results.
Injen CAI, quality, impressive engineering, performance
I've had the CAI installed for about 2 weeks on my 08 Mustang GT. So far I'm extremely happy with the performance of the unit. Take an hour or so to read through the instructions, mock up the intake before you open the hood, and install will be a breeze. The build quality is top notch, it really improves the looks of the engine compartment. The difference in performance is noticeable right away. At idle the engine feels like she's itching to go, at 2000 rpm there's a growl that didn't come stock
