Got my RamAir filter in today along with some other goodies. Quality looking and feeling product. Installation was obviously super straight forward, just undo the four T20 torx screws holding the top of the airbag on, remove the old filter and pop the new one in. I left mine dry, but may lightly oil it down the road with some K&N filter-oil since I already have some.
I immediately noticed an increase in intake volume, especially the stock bypass valve. It almost had the vent-to-atmosphere BOV sound I've always wanted, but not annoyingly loud so as to draw attention. Just loud enough for me to notice the difference, which is what really matters in my opinion. Cheaper than a K&N or Green Filter too, so that's a plus.
