I'm gonna replace my MAf sensor as a matter of course - although I'm hoping it'll help somewhat with some running niggles I'm experiencing.

PArt number is apparently:

22794AA010 METER CP-AIR FLOW.

Which my firendly scoob dealer'll no doubt be happy to supply.

Question is this:

Is the sensor definately the same across the entire range.

I have a JDM '97 WRX Sti V-ltd - as I remember there are two diameters of MAf housing, one is 70ish mm and one is 90ish mm - I know mine's the larger of the two - is it really the same part no for the sensor??

 

BOOT.

Anyone??
