is it OSIR? hows the fit, looks  
Nope i bought it from a German bloke who doesn't speak very good English.  

Its bonded onto a normal diffusor, its like a carbon material with loads of coats of gloss on, almost like a vinyl wrap.  

The fit is like stock but for some reason i need to nip a bit off the plastic clip at one end which is stopping it sitting all the way home on the left side. only a 5 min job when i can be arsed.
