pre/facelift inlet manifold difference?

[k33rxn]

Just clearing something up..

Is there a difference in inlet manifolds between the pre faclift and facelift versions of the ek9?

My pre part number ends in 1 and a friends facelift part number end in 2.
Any differences apart from numbers?

Cheers

All B16B's are identical apart from a few part numbers but these components are identical. The only thing I can think of is the loom and ECU. I think facelift have a very slight longer injector duration in the middle of the rev range.
