and would using a cone filter on the throttle body work for intake I am wanting to save some space but this pic is similar to what i wanna do but i wanna put the filter on the throttle body.

 

Throttle bodies are not worth it, we drive EFI cars and trucks, a throttle body spacer would work if we had a carburated engine. It makes the air denser causing a better burn in a carbed vehicle. Summit is very good about stuff fitting a vehicle check on the site use the left side to select your options as a truck and then you will know

 

any idea if the valve covers will work? they fit mustang 4.6's I want em for my f150.
