Can anyone tell me if or why an exhaust manifold with cats for a BMW 320 with an N46B20 B Engine will or wont fit on a 2008 BMW 2.0 Z4 with an N46B20 engine?
They look identical, the engine block is the same and the sensor points appear to be in exactly the same places.
As the Z4 exhaust manifold looks rarer than hens teeth to obtain yet has a common design flaw that cracks and no doubt will have to find a replacement at some point in the future, was just wondering if anyone could give me a heads up on why this would or would not be an iption?
