JDM STi RA Spec C intake manifold for the 2.0 STi E revision. This intake manifold does not come with TGV valves, improving flow over standard intake manifolds with built-in TGV valves. These can also be used for a custom setup on the DBW vehicles where the customer wants to go back to a throttle cable setup. Will also require the purchase of a throttle body from a earlier STI.

Spec C Fuel rails are necessary for fitment due to differences between USDM and JDM fuel rail lines. They also improve fuel flow performance.
