No, you'd have to replace the whole intake system to see any noticeable gains. Manifold, TB, and Intake. Then you might see 2hp gain from a 67MM TB vs Stock. It isn't like a Fox Body going from a 65mm to a 105mm. Our manifold is the most restrictive part of our intake system and they even did a good job with DSM.
185WHP/153TQ N/A
Turbo Build coming!
