Nick, I had the volant and it does look awesome, but for about half the price you can get the mac or for about the same or a little less, the K&N. It turns out the ones that go on st's were originally designed for a 3.0l ranger. It will give you a large improvement but not what the less expensive Mac will. Just so you know. Heck, I have one sitting in my garage and I would sell it to you cheap, but after knowing it was made for the 3.0l and seeing the difference tha mac makes, I couldnt do it in good consience, a lot of guys are happy with it though, I was until the mac but just wanted to give you the heads up. It does look awesome, that was why I went with it in the begining.You may seriously want to consider the ebay cheapy too.....seriously. Or just by a cone filter, throw it on the stock hose, mine ran better that way than with the volant.
