Hi guys. from Oz.
On my EA81 SPFI (1989) conversion I had a MAF that read low on one reading. So I ordered one from the states that was cheap. Fitted it and had more mid range power. See below. The old one that read low is on the right. The one I replaced it with is identical and on the engine now.
The one on the left is another one that I ordered which was more expensive. It has the same part number being 22680 AA100 AFH38-01 THEN A SERIAL NUMBER LIKE 8217
From then on they are different. Firstly there is a number 3 inside a small cavity near the plug see below and a letter "B" on the case. On the alloy housing there is marked M& whereas the smaller ones are marked M2
The opening of the larger one is huge about 10mm diameter wider and has a wire mesh filter at the filter end.
I was wondering what the larger one is off and if I could use it in my EA81. I would need to modify the air intake to take the larger mount but that is easy.
What are your thoughts?
