I am planning on doing one of the following:
1.) Ebay intake with a 10" K&N cone filter
2.) The factory airbox mod - I will put in a K&N drop-in and then cut an additional hole with a pipe for more air supply.
My two main goals are sound and fuel efficency (and the pleasure of doing mods) any HP gains are a bonus if and should they occur.
My main question about that particular ebay intake (of which I would probably add some kind of heat shield) is that the new tubing is just replacing the factory tubing and the box is deleted. However the engine hat (dont know what else to call it) is still in place (whereas some other intakes remove it and put in a peice of air piping). Could someone elaborate for me on the pros and cons (if any) of havign the longer peice of intake piping that would delete that engine hat?
Would there be a sound difference?
