Question

How must horsepower does the roush cold air intake for v8 add?

Answer 1

Cold air intakes add power, slightly, but they give you your extra power at a higher RPM which you wouldn't normally be at unless your racing. They aren't much good for a daily driver. Check the K&N web site and check their specs for your vehicle. Also your computer will automatically readjust for more air flow and feed more fuel.

Answer 2

about 15 in reality

but if its cold out up to 25

Answer 3

Probably about 10-15 depending on the re-tune.
