Sounds good, provided smoother throttle response, better performance. Easy install, injen makes a good product. No complaints.

Installed this product on my 2011 Mazda 6i and it is great! Installation was super simple with detailed pictures It adds a really throaty tone above 3k rpm and noticeable throttle response. Will be testing the supposed fuel efficiency. Suggest cleaning the MAF sensor when you install it though, since you will be swapping it over anyway. Gotta have a way to measure all that new air the engine is getting!

I have used K&N filters on all my vehicle for the past 15+ years but this is the first CAI system I've installed. It is very easy to install for anyone who does simple maintenance. You can notice the improved acceleration, it works. I am pleasantly surprised that it DOES increase the mileage in my Mazda 6 by a couple MPG. There is a strange 'growl' at low rpms but it shouldn't be so bad that you would want to 'unload it' as a read one reviewer say. Using the Sport mode of the transmission makes that go away. Very happy with the product.
