i wouldnt even bother with an intake on a 4cyl.
You floor the car, you hear the noise from the intake yet the car isnt really going anywhere. I had one and took it off. I prefer the quiet drive now.

ohh, those ebay intakes suck. The piping sucks and the rubber clamp things will wear and break sooner than later.
Better off paying the extra bucks for at least an AEM one.
