I only got the air raid jr. tube and the replacement k&n filter for my 4.6. I am hoping to gain a little hp and better fuel mileage. I will post results when I get it put on.

 

I run this setup on a 5.4. I have no problems and acutally like it...sounds deeper when accelerating, but other than that...its a minor mod. The Airraid Jr. tube is definately less restrictive than the stock one...so it seems!

 

great choice you'll be happyM.W.
