Seems like in bottom end hp/tq is basicly the same, probably a 1-2 hp/tq raise in the curve.

Around 4.5k and up you get around a 4-7 hp raise and 3-4 tq raise.

But around 6.5-7k you got 15 hp and 12 tq.

Now what im interested in learning is if was the filters that gave the hp/tq increase and not the actual CAI. Going from cotton / foam vs a paper filter is a lot less restrictive.

Its not bad for a basic bolt on.

Maybe if you tuned it out you could get a little bit more out of it. And smoothen out those curves, because thats just really bouncy.

Thats $120 per hp if you are looking at the 15 hp gain for 500 rpms.
