Well I have been using the Lukey panel filter for almost a week now. And I can definitely say it was worth the buy. Much better power in the higher revs and a noticeable sucking/popping sound around 5,000rpm. And there is no increase in induction noise in the lower revs so you can still hear the turbo whistle.
Anyway I will still be going for a pod filter set up later on. I will all so be going for a JJR turbo back exhaust too.
