I run the HKS super hybrid filter on my STX RX8 build and love it. It is a completely different style of filter element from that of K&N and other major players in the drop in filter world. It is foam with 3 different density layers. The flow and filtration seem to be the best of both worlds. Plus there is no oiling involved, which if others are over oiled can cause damage to MAF sensors.
