id say. so just the 5.4L throttle body and gasket thing? what vehicles came with that? is it just the f-150's or what? which model and years did this come on?

Well I don't really know if you can claim 8hp until you dyno, but I almost guarntee you won't see 8hp at the wheels with a change like that. But there will be some improvement in the car.

Thats awesome that you found that. Lets see some pics of what it looks like.

The best way to smoothy increase your power when dealing with intake is to change all three items at once: throttle body, plenum and CIA. All these parts work much better when they are ganged together. Choice of parts and at what price is up to you.

Ohhhh I was thinking you used a 5.4 plenum.....you used the TB....still cool tho. But TB's don't really add too much power...its mostly the a/m plenum.
