S5 MAS on an S4?

Can I replace my flapper MAS with the S5 version?

Thanks.

I was under the impression the S5 version wasn't a flapper style, there for inhibited airflow less. Is this not the case?

Is isnt a flapper style, but rather a cone-style. It has a plastic cone that the air pushes back, which it takes readings from. IMO it is more restrictive than the S4 one, but if you would really like to try it, I have the wiring diagrams for both which you can use to rewire the S4 harness to work with the S5 AFM.

I'll just take your word for it, thanks for the info.

Anyone know what kind of signal the ECU reads from the AMS? Wonder if you could adapt a GM style MAF and use a MAF Translator with it, like a lot of the DSM guys do. Just thinking.
