hp gains

adding a cold air intake and exhaust on d17a2 is good for how many hp/ft lbs.. I know there are many variables but in general what would the gains be.

5-7hp, that's being really generous to. That is assuming you have headers, high flow cat, and a good cat back exhaust system

5-7 for an intake? That's being extremely generous.

I would think more along the lines of 1-2 hp gain. Nothing noticeable.

3hp max, but it'll sound a lot better and I'm sure better airflow will contribute to slightly better gas mileage.

either way it helps and it's relatively cheap
