On the link you posted, there are some picture of how the baffles look on the inside of that cover. They look exactly the same as the baffles that were on my original plastic cover. I have since put the omix aluminum one on, it has different baffles, but I think that the omix has less breathing restriction than the original plastic one. My car has terrible blowby, it constantly puffs oily gas (not gasoline) into the air cleaner. To me it seems to breath just as good as the plastic one did. It must be breathing good if the blowby pressure hasn't caused a leak yet. So, to answer your question, no, I don't think that cover is worth it. I would buy the standard aluminum one that most people here seam to get, mine cost $90.
