At the 40th event in Nashville I asked the Edelbrock rep when we were going to get an intake for the 4.6. He said they've had a couple of prototypes but they're not making any power over stock. He said they're not going to make one unless they can show an increase with it. I asked him why people were willing to pay 1200+ for the bullit intake and he didn't really have an answer for that. 

You might only gain a couple HP at peak with a Bullitt intake, but your gains up top and down low are even more impressive. The Bullitt intake doesn't crap out after you hit peak HP as bad as the stock setup does.
