Finally, an aftermarket intake manifold that delivers the goods! On back to back testing with one of our high-power cars, we saw peak power rise by more than 30 hp. Even naturally aspirated cars see an improvement.
The manifold has very long runners with well-designed bellmouths to feed hungry cylinders. The walls are fairly thick so you can port to your heart's content. The two-piece design allows you to add a spacer to increase the volume of the plenum. The throttle body opening is 68mm if you want to run a big throttle body, and the flange design allows you to fit this manifold to either NA or NB heads and can use either stock or Skunk2 throttle bodies. It includes a phenolic spacer to prevent heat transfer from the head to the manifold.
Sorry, it won't fit a 1.6. It will fit an NA8 head, but you will need to use an aftermarket fuel rail.
The 30 hp gain was on back-to-back dyno tests of our 2.0 R&D car with a GT3070 turbo. We used a stock throttle body for both runs, and the VTCS manifold had the butterflies removed.
Out of stock until June 2018.
