Getting the ford racing intake is great for FI , but won't hurt you if it's still N/A. Just won't see many if any gains unless you have all the bolt on products you can buy i.e Heads,Cams,long tubes . Delete plates are cheaper than the intake and are supposed to see some gaines. Just google ford racing intake there are a few articles out there that tell you what the gains were on that intake
the ford racing intake is for if you have cams or forced induction.
There is a article out there with dyno runs, you will lose alot of torque.
I would do the plates hands down. They even sell them with nitrous ports.
