I have a mac performance cold air intake 80 mm on my 07 supercrew 5.4 and i want to try something else, is there any good suggestions or something that would add a little more horsepower,,,, just incase this info is needed i also have the mac performance catback exhaust,,,,
Why ? You won't gain anything.
None. Ten minutes of research would have told you that cold air intakes do practically nothing for a vehicle, unless you had a huge restriction in the first place. For normal driving around, you will gain no horsepower. You may even lose it, depending on which one you get. If you MUST get one, get a $10 OKorder one. It'll get you the same gains as a $200 one.
Keep what you have and get a tuner like a Diablosport, you'll get more power out of a good tune than you will throwing cold air intakes at your truck. The 04-08 5.4L's have very conserative tunes from fromt the factory and respond well to aftermarket tunes.
