Cast iron nickel alloy turbocharger exhaust manifold – for 1.8T 150–180 hp engines

Suitable for all 1.8T engines (150-180 hp), such as Audi A3, Audi A4, VW Passat, Golf 4, Seat, etc.

This updated exhaust manifold offers a clear performance improvement thanks to enlarged channels (41 mm). In addition, the flanges are grooved, which significantly improves crack resistance.

Select by engine type:

• Transversely mounted engine – e.g. Golf 4, Audi A3

• Longitudinal engine – e.g. Passat, Audi A4

Order the appropriate cylinder head gasket directly at the same time.

Installation information

Due to the bulbous design, the two upper nuts are a bit difficult to reach. However, installation can be done by an experienced installer even with the engine in place.
We recommend using small spanner turbo nuts to make installation easier.

Additionally, longer bolts are needed — we recommend Inconel bolts for optimal heat resistance.

Not compatible:

❌ 209 hp and 225 hp with Quattro models
❌ K04-023 with turbocharger modifications
