That LF3313 is real but that does not mean the rest will be.

As long as they have the MADE IN USA or other country of origin by the filter diagram on the filter and are fully wrapped in plastic and have the zulu date code on the top of the filter you know your good to go. So far have not seen a real LF3564 yet. Just check them before you buy them. Lots of places mix the real with other filters that are fake.

But if they happen to have the real deal post them up. But I would ask them to verify before ordering them, because they probably get them from Pacer.
