Subaru Sti Spec C Manifold Risers - Top Feed

Often called 'TGV's,' these high flow manifold risers are found on the highly coveted JDM Impreza STi Spec C.

Overview

  • These units eliminate the TGVs (tumble generator valves) found in the stock manifold risers, thus increasing airflow by ~20%!
  • With any purchase of Spec C risers we will include a free off the shelf COBB AP map that turns off the associated check engine lights.
  • Price is for a pair. We can sell them individually on a special order basis only.
  • Photo is a depiction, actual unit will vary where the injectors go

Applications:

  • Subaru WRX 2.0L 2002-2005
  • Subaru WRX 2.5L 2007
  • Subaru STi 2.5L 2007-2017*

Minor modification required for 2.5L turbo intake manifolds (see photo of red intake below). The 2 center holes will need to be enlarged by ~2mm. Otherwise, this is a direct bolt on part (fuel rails bolt right up, etc).
