Product Features:

  •   Factory Turbo Orientation - Oil Feed, Oil Drain and Water Lines are all included, and the orientation is in an identical position to the factory setup, allowing for easy re- fitment.
  •   Factory Turbo Position - These Turbochargers still look very similar to a factory unit, and utilize the factory manifold, and exhaust system.
