They are selling them on ebay: Ebay listing . Is this all that I need? In what areas would I see better performance, and by how much? Thanks.

 

is there anything wrong with your engine right now? is it smoking or loosing compression? if not then you shouldn't have to replace anything. If your looking to increase performance a little then your best bet is to get a dynojet kit, a k&n air filter and a new exhaust.

 

Alright I'll look into that. Thank you.
