Had two European intake manifolds for the 2.9 shipped over from the UK. Just a photo thread showing differences in three different twin throttle body 2.9 upper manifolds - two generations of Euro manifolds versus the American version.

Have a Merkur lower on the way (very different port shape). Will update with photos of lower intake differences as well.

Biggest differences at a glance:

No EGR port on the UK throttle body

No IAT sensor port in UK manifolds

Missing center rear vacuum port in both UK manifolds. The Merkur Scorpio intake has a drilled and tapped port in the back that allows both sides of the manifold to equalize pressure. This is for the MAP sensor. This port is blank on both UK manifolds. Guessing this is due to most European cars using vane air meters versus the American cars using MAP sensors.

Black UK manifold has a different PCV port

Euro throttle body missing cruise control cam and return spring.

The gaskets on one if the European manifolds contain two extra holes that are not present in the Ranger lower. Still searching for the lower that gasket fits.




More to come

Interesting. I'm still learning the 2.9. Back in one after 21 years.
