WOW! I used to have a cheaper cold air intake in my 2005 Scion xB and haven't noticed any change or improvement. As soon as I applied it I noticed the difference immediately. I have much better acceleration and I can't believe it, but my little 100hp box has a voice now. I already have a good TRD exhaust that sounds good in the rear, but now the engine sounds bad. When you increase the revs it sounds so great. It's worth the money. I don't have to put it to the test to see the difference, I can feel it every time I step on the gas. I like it!
