I bought an aem tru-boost and wideband from a guy and he included this too. I cant remeber if it was for a WRX/Sti or for the evo?

Anybody seen one of these, I lost the paperwork saying what it was. (sorry for the crappy Iphone picture)

 

Maybe to dim the gauge? I have no idea. lulz :P

 

I just installed a tru boost and that parts not included. Maybe it's part of the wideband??

 

Not part of the wideband..I didn't get this with mine.

 

nah its not involved with wideband or boost. its some enhancer for something haha just lost the papers

 

^ lol I'm pretty sure it's used to dim the gauges...

 

i think i remembered something about fuel or exhaust
