Can anyone recommend a good CAI? I was looking and K&N's website but they seem to be very similar to what I have installed minus the bracket by the filter which may block some of the heat but certainly not all.
To be honest I would use what you have but just make up a heat shield for it. Can you post a pic of what you have currently? It wouldn't be worth the money to get another one. I've made heat shields out of thin aluminum sheet that you can buy at local hardware stores or home improvement stores cheap, and just used tin snips to cut, and a T square or similar to make nice bends. Cheap, and it works decent. Then just run some sort of weatherstripping on the edges. It doesn't need to be perfectly sealed, but the better sealed it is the better it will perform. If you want a new CAI I'd look at getting an airraid (either the full $ kit or the jr. kit), volant, or afe.
