Is it possible to replace the elements of the Airinx filter with other colours?
If it is, where can i get them?
I have the original yellow one at the moment and it's a bit.. Ehhmm.. You know.. Yellow..

 

the yellow one is the J-spec one. But since your in Europe there should be a local shop that can order them from greddy for you. The american version comes with a blue filter element if im not mistaken. So you may be able to get a blue filter.
