I'm wondering if the MAF on the new WRX is an improved version over what was supplied on the North American market MY99 2.5RS. The MY99 Hot film MAF unit had a reputation for failure, and is know to give inaccurate readings when paired with certain aftermarket intakes.

Bosch has since received a US patent on improvements to that old design. I'm curious as to whether or not the MAF unit on the new WRX has these improvements incorporated. I should be able to tell from a picture of the inner sensor housing.

Is there anybody here would could take such a picture?

Scott - the failures were just a bad batch of parts..happens all the time on anew design. I have had my 32 MAF in my car for a year and a half..turbo'd and all, with nary a problme. From 2000 on, I assume t WRX converted to the MAP that the '00 and up 2.5RS's got.

Plus, the MAF from, say a Version 5 is the same as our 2.5 one...I looked into this when blew my first one; part numbers were the same.
