i know it's very unlikely it would work but-- has anyone tried to use a v6 mpv air flow meter on a s4 tII? it looks identical and the flapper door spring feels similar tension as my stock one. it feels stronger than the n/a spring. i got one for free and i know the engine it came off of ran good. haven't tested against rx fsm or tried it yet. my only reasoning is that working afm are hard to find cheap.

 

they aren't that hard to find, you just have to look in the right place. Or redefine your definition of cheap.
