Whats the diff?

Which one is better?

I like the ram air better because of the price difference. Cold airs usually tend to give more hp but not much. I would rather save a hundred bucks rather than having another 2 hp.

Yeah but if future plans are necessary cold air would be well worth it.

You could make both with PVC pipes and then you could chose. It would not cost that much.

A few degrees less doesn't justify the cost.
