About this part

What it is and why it is made that way

A manifold brings several passages together in one body, and the fewer welds it has, the fewer places it can leak. Die casting forms the passages in the cavity in a single shot, and the port faces and mounting faces are machined afterwards so the joints actually seal.

  • Internal passages formed by core pull in the die
  • Port and mounting faces machined flat
  • Pressure tested on request
  • Supplied with material certificate and a dimensional report
