May I ask why you're doing this to a 520 and what benefit do you expect?

No, don't take the AFM apart ... it needs to stay in its factory housing to function correctly.

As Torque says, you can't disassemble the AFM unit. It is calibrated to YOUR engine and any significant changes to it will instantly ruin the mixture. I have played with my AFM & intake over the last 5 years or so, along with some other guys here on the forum and I can happily tell you that you won't gain a single BHP - it is easier to lose power than dial up some more. This sounds like some dodgy Vauxhall/GM trick to me lol!

HTH,
