Buy it for looks and sound...not so much for performance.
We picked up a K&N Typhoon for my kid's 14 Chevy Cruze. It was fairly easy to install with basic tools and it looks pretty awesome in the engine bay. It also made the car sound cool with a deep growl on acceleration and a turbo whistle when you let off. It kinda made the throttle feel a little snappier but no noticeable horsepower increases. Like I said in the title, buy it for looks and sound but don't expect to turn your Cruze into a rocket ship just by adding this short ram intake!
