This manifold will fit all VW 2.5L engines with the electric power steering system. Some later style engines use a hydraulic power steering pump, which sits right below the factory intake manifold. If your car is equipped with a hydraulic power steering pump, this manifold will not fit.

Automatic vehicles require a matching IE TCU Transmission tune to allow high revving of the automatic transmission. The stock automatic tune has internal transmission rev limit controllers that shift before the manifold and software can make the extra power gained through the upgrade. IE's Auto Transmission Tune removes this limiter allowing full advantage of the manifold & tune.
