Does anybody know the exact name of the little blck box in the picture? i have looked in manuels, pictures and still dont know what it is.
Thanks

 

Boost sensor for TII..N318
or if it is on an s4 N/A it is a N326 or N327 Pressure sensor.

 

looks like you're missing the engine too. haha.

I think it's called the boost sensor regardless if it's NA or Turbo, & yes the numbers posted above are correct. There's a second "pressure" sensor behind the pass side kick panel

 

Actually, to nitpick, it's a boost sensor if the car is NA, and a pressure sensor if the car is a TII. This is how it's listed in Mazda's documentation. Go figure, eh?

 

Thanks guys ! and this was a photo i just pulled of google lol
