MAF and air filter?

[andy10v]

I would rather have no screen than one that is falling apart, then get one out a dead maf etc.

[Rikki Kitto]

True, anyone got a dead MAF kicking about

[andy10v]

Is there a screen a both ends? I cant remember, but seem to remember removing a good down stream screen from a maf on something to replace a damaged up stream one?

I believe it's only one screen at the front can't remember now..

Sorry. Your memory is fubar.

Stock = screens on both ends

Thanks Dave

Hope I don't get banned for asking this, is the only difference between RS2 S2 mafs the screens? surely not?

G70 Mass Airflow (MAF) sensor info

I took both screens on mine MAF out and there is a noticeable difference at the top. Now with the RS2 Turbo, EM and ECU works fine as well.

Thanks they are the same then, just change the grill to RS2 type and hey presto

Very similar electronically. Not the same (but close) flow-wise. RS2 MAF probably better at higher flows.

[Rikki Kitto]

I can confirm from factory data now, that they are completely identical electrically.The difference on that graph is likely because not two brand new units were compared and because they are within a 3% error margin anyway.That graph to me looks like they used an AAN maf with some miles on and a brand new ADU MAF."

[doncecone]

And to make it more credible a guy did the flow calulation and gues what ?

Nice find

[doncecone]

You can also read his next article where he also find a way do make even better flow in the airbox making kind of RAM system. I think there modifications are effential for anyony running RS2 setup with chip on AAN standart airbox and MAF.
