Call STILLEN they will explain it to you. Get the facts straight from the source. Then maybe your opinion on the matter could be different. Please report back when you have factual basis for your opinions.IMO, ALL filters box whatever must use the stock MAF diameter so I'm not buying (pun intended) any massive changes. What if a box does not use the stock MAF diameter? simple the MAF reading is hosed which ain't good for power. One probably could just leave hood open, take off filer and prop the box up and too what the MAX HP any box filter whatever would do. Last point, any improvement to the induction of a turbo just saves a little HP to drive the turbine, the turbo will reach (in this application) desired boost and then open wastegate, the slight heat injected into the air stream via the slightly more HP needed to drive the compressor is wicked away by large intercooler. If one is not increase boost (regulated by ECU program) how is so much HP gained (about 6% to 8% HP per PSI of boost). Boosted is really a measurement of restriction in the air entering the engine, until I see a boost plot with all these magical boxes, I'll remain skeptical. Last point the ECU slowly learns boost, ignition, cam, and injection offsets, it is not surprising to change something and see a big jump in HP, only to have it turned away (a dyno is a no load one shot device). Pull the ecu fuse first dyno and between every run after so the ECU is running on base tune, last dyno run put the stock box back-on and lets us see what you really get. But then you could not run fancy boxes.
My Camaro has gone up 30% HP NA and I got the stock box, the Callaway Camaro runs the stock box with a hole cut in the bottom, my supercharged Miata ND runs the stock box, my Integra Type R runs the stock box (bores sleeved stroked B20 VTEC), heck I can't think of ANYTHING that I have that does not run the stock box if able (my Camaro has a built sleeved LT1 with FA supercharger on it no so stock box won't fit... but if it did I'd run it).
Last, I'm a little leery of gauzed oiled filters and dust / sand etc. I can't think of any factory or expensive tuner that uses them. I got a K&N filter with my Edelbrock Miata supercharger and just tossed it in the trash, thick paper is good for me, so what I lose a few HP (roots supercharger more sensitive to intake restriction).
Nutshell, not much there there IMO, TRD is red and that is always faster, so others are more open so you can have more turbo sound, all use stock MAF size, so other than a ever so slightly less restrictive filter albeit one that is iffy compared to a good thick paper one.. may free up a few HP needed to drive the compressor, which may help spool but since the boost is limited by programing, somebody better tell me how it is gaining HP.
