Other than pure greed (unless I am missing something!) why are the CAI's for the new mustangs so gdang expensive? It would be relatively easy to fashion a sealed off area where the stock filter is and use a cone. I did one on a RX7 using rigid insulation. Duplicate the stock hose routing with silicone or smooth rubber.

What am I missing?

Tnx Fred

 

I wouldn't call $300 expensive. That's just me.

 

Reason cais are so expensive for the new mustangs is simple, manufactures are trying to cash in on what people want. Right now there are not a lot of options for the new mustang, manufacturers know this therfore they can charge whatever they want. Like I said on anther post, a more expensive cai doesn't do squat over a chep one. Its still basically a tube that has a lifetime airfilter on the tip, all of which are fairly the same, even the ram air kits. All they do is allow greater airflow to enter the engine, but because of your small stock throttle body you can only put so much air into the engine in the first place. Just because one ad says "will raise rwhp by up to 15+" and another says will raise rwhp up to 20+" there is no differece between the two, other than maybe a little style and the airfilter. Both will give you about 5-10 rwhp, nothing more unless you have a high flow throttle body and MAF. So if you can find one on ebay for cheap, and they do have them, buy it because you will get the same results with a cheap ebay kit as you will with a K&N kit, or an AEM system promise you. I do recomend the K&N air filter only because it is a little better in quality than the rest.
