It's crap. Don't bother they don't really work and the sure as hell aren't as good as the site says they are.

Yea, I don't believe I will get 30hp and 10 more miles to the gallon, but even if I were to get 3-4more mpg, I think it would be worth it.

The problem is that if it is like the others I have seen it is only on at wide open throttle. This means at any other time it is just an obstruction in your intake. But if you do try it and it gets you good results let me know so i can stop telling everyone what a huge piece of crap it is.

A guy on my street has a 2003 Tiburon Tuscani and put it in to give it a try, he told me that it wasn't quite as good as they claimed but it did noticably increase mileage and hp. He recommended it to me but he's not exactly a tuner guy he got it more for the mileage.

I have herd different things. the most is decreases performance, but increase mileage like 20 miles a tank..
