I spent most of last night admiring peoples engines and how good there intake systems looked. I want to insert new pipes and air filters on the end, similar to the below pictures. I don't have a clue what Size pipes/Air filters i am going to need. Can someone please help? I would like to know the lenght and diameter of the pipes and would a 3" Filter on the ends work?

Just to add: I want to run the air filters closed to the front of the Grill to get cooler air, I know there is problems having them next to a boiling engine

Thanks
