Tried to put on standart mugen onroad foam filter without insbox and it dosnt fit as well.
Are there any special RB filters, that should be used? By EFRA rules insbox is a must, so i would like to know how to fit that thing on.
WoW! INS box on .12, not normal in USA. If rules specify you must run, I would try the small INS box. You may have to research as we only make standard size.
