Use of split-spray injectors in 2-valve head

Use of split-spray injectors in 2-valve head

Use of split-spray injectors in 2-valve head

(OP)
I would think that using split-stream injectors (like those used in a 4-valve per cylinder head) in a 2-valve head would result in more wall wetting.

The motor in this case is a BMW M20B25 (bathtub chamber, 2-valve) and the split-stream injectors from a M50B25 engine (pentroof, 4-valve).

People are using these newer injectors to replace clogged original injectors on high-milage engines.  I would think it would be better to source injectors of a single-stream variety.

Any thoughts as to performance or emissions?

Thanks
