S4 T2 boost sensor vac hose
 

Does anybody know where I can get the small pellet with the hole in it, that goes in the vac hose for the boost sensor.

call mazdatrix. you could probably make one too.

Dealership!

OK. Is the pellet metal or plastic? What size is the hole? Has anybody actually succeeded in drilling a hole in a pellet of that size?

SEARCH for the word ORIFICE and NZCONVERTIBLE

Or SEARCH the parts breakdown manual INDEX for ORIFICE and get the part number.

I had no idea about this until I just searched it, and now I'm an expert :icon_tup:

See what searching does!

Anyways, it's a restrictor inside the hose to the map sensor that's supposed to smooth out vacuum fluctuations so the map sensor doesn't make the ecu freak out. It's 0.5mm, so drill that size hole in anything that you can shove in the hose, closer to the intake manifold so the rest of the hose can do its buffering job too.

Just found this after cruising through Mazdatrix's website too:
