An inlet manifold to suit the BMW M42/44 inline 4 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 type mounting and can be made with 45mm, 48mm or 50mm bore mounting plates.

The spacing between throttle bodies 2-3 is 93mm, however this can be adjusted if required (depending on your linkage). Please specify throttle body port size, if this hasnt been specified we will automatically send a 45mm port.

Note that this manifold is intended for throttle bodies (EFI) and is not suitable for carburettors due to the approximate 10deg upward mounting angle. Please contact us if you require a carburettor type manifold where the carbs must be horizontal.

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 accommodated, 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.
