I'm doing the best I can, my estrella, I just got the original filter, I bought it from megazip.
I have a doubt, the filter is a little bigger compared to the grid where it is additionally placed, which has two faces, one of sponge and the other face of a fiber that is impregnated with oil, I need to know if the sponge goes to the engine or outward.

thanks

Maybe you've found your way till now.. Anyway, the sponged face should be on the inside. Also, don't worry if you have to cut it so it can fit.
