Water Pump (26 Teeth) for Audi RS2 / S2 / S4 / S6 – Increased Flow Rate
This water pump serves as a replacement for the discontinued RS2 water pump with part number 034 121 004 BX.
The pump is modified in-house to 26 teeth on the drive sprocket to achieve a higher flow rate compared to the standard 20V pumps (29 teeth).
Particularly in performance-modified engines such as the S2 ABY, S4 or S6 C4, this modification is especially worthwhile, as it significantly improves cooling capacity – a decisive advantage with tuning builds and increased thermal load.
Depending on the delivery batch, the supplied version may vary slightly, as different batches are sourced from the manufacturer. There are, however, no differences in performance – both variants use metal impellers for maximum durability.
Key Benefits:
-
Replacement for discontinued RS2 water pump (034 121 004 BX)
-
Modified in-house to 26 teeth for increased flow rate
-
Ideal for tuned or thermally stressed engines
-
Durable design with metal impeller
