respectfully disagree, keeping in mind how tightly woven that screen is both front and rear of the MAF, and so it would have to be something pretty dang tiny to get through, especially past the air-filter which is supposed to be very tightly sealed. If you really examine that screen, it wouldn't take a whole lot more metal material to make that thing a solid disc, lol. Any issue would be at low-throttle, low RPM (idle). I've read quite a lot of references to the MAF screen actually being a hindrance at around 400 horsepower or more (again, not just Z32's). But that's just me. Whatever Tanley decides is fine :)
