Good aftermarket manifold..although not made to the same tolerances as original.
Left hand side of manifold needed trimming to allow it to seat correctly. And right hand side needed a few millimetres removing to allow fitting of egr cooler.
A tricky job on an ml not helped by having to pull the manifold out a few times but worth the saving in costs against a dealer part.
This represents value for money. Merc part was £800 so this was a no brainier. The mechanic told me it needed ‘fettling’ to get it to fit. A bit of grinding to remove a mould seem. But it you build in the extra time with your mechanic then it is excellent value for money.
