I am in the process of converting my car to dual intake. To complete the job, in addition to the Selin items, I also needed another MAF and filter. Bought one from a tt.net member, never considering it might be an aftermarket unit. Interestingly both the one a just bought and the one in my car have the decal that says "JECS" and the NIssan logo on the body. Although you claim MAFs with this decal are fake, the elements inside resemble the real OEM units in the pictures you posted. Guess I may have a hybrid, two actually.
