The independent tests I've seen (and quoted) say otherwise.

Certainly one should weigh benefits and disadvantages. All I suggested was
to be aware that one of the disadvantages is more dirt in your engine.

I wasn't there, but he examined the carbs under a microscope, and decided
they were filter fibers. He didn't believe it either, seemed more
reasonable that it was dirt in the rainwater, but that was his conclusion.

A 914/6 doesn't give a lot of choice in that area, unless you want to cut
the body apart to install a Baja-style air intake. The filters were at the
top of the engine compartment (on top of the downdraft carbs), comparable to
where most of us have our air filters.

Again, I wasn't there. But knowing my friend and how fanatic he is about
his Porsche, I seriously doubt that he had not been servicing them as
recommended by K&N.

Perhaps they stop sloughing after a certain number of washings? Or perhaps
it has to do with the water being forced through the filter by the suction
of the engine, rather than being "gently drained by gravity" as K&N
specifies.

And I have no problem with that. Get the facts, then make your own
decision. The fact is that every independent test shows the K&N filters are
inferior at keeping dirt out of the engine.
