Whats inside a MAF?

Managed to get a maf and clear side repeaters from a breakers for a fiver. And the MAF (
bosch F 00C 2G2 030) works perfectly.... engine warning light now a thing of the past..... for now at least.

Today I split my old maf open in my usual "I want to know how it works" way and was greeted with this. The internal circuits are enclosed in a thick gel. I wondered if opening would allow me to clean the element properly but its not a re-sealable case.

The small metal part that is heated (not the wire I expected) was cracked. I'd suggest the heating along with oily muck build up will overheat the part. Maybe regular cleaning and removing oily residue will extend the life of the maf.

Just thought I'd share as I have never seen inside and more than likely.... neither have you.
