Which one do you guys think I should get? I don't care about cosmetic value, just raw performance. I've heard the CAI causes the car to sound better like it has a growl. What would you say this sounds like? American V8, Honda I4, or what? I'm just guessing here, but since the CAI draws in cold air from outside the engine bay, wouldn't it put forth more power? Help me out guys!

 

You need to drill a hole to put in the CAI. You don't need one for the popcharger.

Both of them growl. But I like my popcharger. Didn't want to go through the hassle of drilling the hole.

Other than that, they put out approx the same amount of hp.

It hasn't been proven that either provides significantly more hp than the other. Read this and draw your own conclusions: http://vbxmaxima.8m.com/caivssi.html
