Whats the diffrence in power gains from cold air to ram air????

 

I've seen posts like this a few times. Everyone seems to think that they are about the same. Some say that Ram air produces more HP @ high rpms. I just put Ram air on my 96 TA and I can tell a big difference over my K&N FIPK.

 

Its hard to measure their difference on a dyno since you have to be moving for the ram air to actually do as its name intends. But in my opinion the cold air should make more power since its filter has more surface area.
