I'm looking at getting a cold air intake for my Mazda 3 and have a couple questions about a couple I have been looking at. I'm looking at a K&N 69 Typhoon cold air intake, also a Corksport Power Series short ram intake. What is the difference between the two of them and how much of a difference would they make for my car?
