Nothing lost, nothing gained.
This Airaid MIT was simple to install. Pull off your old stock plumbing and replace with this. The design is supposed to allow more air flow into your throttle body thus increasing air flow into your engine and raising your MPG and power. However it has been 2 weeks since I installed the MIT, and I have seen ZERO MPG increase, ZERO power increase. I guess, I have to be thankful, it didn't decrease my engines efficiency any.
