Audi S2 / RS2 / 200 3B Water Manifold 034121187 / 034131193A - PRE-ORDER


We are planning to reproduce the obsolete Audi S2 / RS2 / quattro RR water manifold part number 034121187. The parts will be produced via sand casting & CNC machining.

This project will only proceed if we get adequate buy-in from the community to cover the cost of the foundry tooling and initial batch casting costs, heat treatment and finish CNC machining. Therefore, this will only be available on a pre-order basis – we will only produce these parts for those that pre-order & there will NOT be surplus available to purchase afterwards – we will only produce as many as are ordered. The minimum quantity is 40 units. There is no maximum.

The Pre-Order cost per part will be £225 plus shipping & local duties / taxes. 

Please contact us directly for dealer / business pricing. Please note minimum order for dealer pricing is 10+ units.


  • Pre-Order the part through our e-store. We ship worldwide.
  • Once pre-orders for 40+ units are received we will trigger the production process. As you can see we have the part CAD modelled. We also have the production of the foundry tooling designed, modelled & ready to machine.
  • Production timescale to delivery will be 6-10 weeks from initiation of production. Orders will be shipped in order of receipt. Shipping to remote areas will likely result in longer delivery timescales.
  • Discounted Pre-Orders will only be accepted until 31st March 2024. Orders after this time will be charged at full retail price.
  • Orders are subject to our standard e-store terms & conditions. You will need to agree to these T&Cs during order checkout through our e-store.

Please help to progress this project by sharing this with any local / national Audi 5cyl community groups and non-English native language pages / platforms.


  • Direct 1:1 replacement for original factory parts.
  • Castings produced from pattern equipment in accordance to IS0 8062-3: 2007 DCTG 8 tolerance standard.
