What is the best and least expensive way to get more power out of my 4.6

 

Sounds like you need a monthly budget. This question is asked daily. Start with at least a K&N air filter or a cold air intake, upgrade your exhaust for a nice sound and a little more HP. Horsepower costs money. Save for a few months and do some research to get an idea how far you want to go. If you said you had $800 to spend you might get a better response. You have to have a budget If you want more.

 

do some gears. wont get you more hp but it will feel like a ton of hp. full exhaust too

 

nitrous is the best way to get a lot more power for cheap. like the others said, also look into rear end gears and exhaust.
