so the little black plastic spacer piece coming off the top of the thermostat neck located right under the radiater cap seams to not have a lip on the top anymore therefore not sealing correctly anymore and im tired of smelling like cotton candy going down the road.

I got that same one, from MazdaTrix.

Love it. Word of advice, get the o-ring that it needs too (they don't include it).

 

anyone know where to get the cheap little plastic piece

 

new? i dont think you will find it at a parts store...you will need to get an OEM one. i would just get the metal one or another used one.

 

Try the dealership. Just make sure you get the S4 version, since the S5 has no overflow bung like the ones shown above.

 

i have the plastic ones...w/ and w/o overflow nipple...
