An Inlet Manifold for fitment to the proton 4G92 engine, TIG welded in aluminium and fully internally ground to ensure optimum flow and performance. This manifold is designed for the standard Weber/Jenvey DCOE mounting and can be made with 40mm, 45mm or 48mm bore mounting plates. The spacing between Bodies 2-3 is 97mm, however this can be adjusted if required (depending on your linkage). The angle of this manifold is 20 degrees and thus NOT suitable for DCOE/DHLA carburettors (see our other shop items for carb type manifolds).

The manifold includes a single servo connection - these can be blanked off if not required, please advise when ordering.

Technical drawings are available on request and custom lengths and heights can be accomodated, please message us with your requirements.

This item is made to order and therefore on a 10 working day lead time. If you require any additional vacuum take-offs adding to the manifold or a coolant connection these are easily added - please contact us.
