i have a 4150 intake with a adapter to a dom. 4500. How much would i benefit putting a 4500 intake on and doing away with adapter ??
I think he's talking about swapping intakes from a 4150 to a 4500 intake, not adding the adapter to a 4150.X2, need more info.
To do most of these style intakes right, you are going to need to do more than just put the adapter on... You will need to mill out the plenum and fully port the intake to see big gains. Whats the full combo? What RPM? what's the app.? JHope this helps
