Intake for stock twins?

I own the A'Pexi Power Intake (installed by the previous owner) – something else to consider is that filter replacements can be expensive.
For example, the replacement filters are over $80 each on the A'Pexi intake, and there are two of them. They are not designed to be cleaned, unlike some other filters.

Interesting. This thread got me browsing for one and thought it was either NLA or a new design. But sometimes the pictures are hard to tell if the pic is actually of the RX7 version of their product. I probably just don't know how to search well haha

the HKS is like this too, they would like you to change filters at 6k in kilometers, basically when you change oil
at least the HKS filters are inexpensive!

Autoexe with Abflug bumper with metal divider, dividing intake upper air from lower radiator air in the bumper = ZERO hot radiator air or hot under hood air entering the engine. Only fresh outside air. Also, have a 600 cfm intake puller fan mounted inside the Autoexe with a temperature-controlled fan speed system (don't need the fan pulling when the car is moving)

They have two on the site. One is discontinued and the other you can buy. I just received mine in the mail. They are built to order so expect about 2 months for it to arrive.

the bigger issue for me is the extra air noise before the transition at 4500rpm. I just want to hear the rotary, not pressure bleeding off turbos constantly.

yes, it does unfortunately. I don’t really want the boy racer sound, and the blow off sounds with relatively easy releases of throttle.

Probably not any quieter in practice than running the twin cone designs mentioned above.
It’s not like it sounds like you’re running an 80mm turbo at 30psi, but you definitely can hear the turbine whistle. Blow off sounds are maybe a bit quieter than an external blow off would be, but still very noticeable to the driver.

SP cold air airbox should still be available if running a smic. Uses the stock or aftermarket panel filter - those Japanese pod filters only seem to stop large bugs and fall apart at the drop of a hat. Charge relief is vented though.....probably could plumb to the airpump inlet if that is deleted.

You can help quiet down the Autoexe airbox with an internal insulating/sound spray. If you look closely at my picture you can see it. It is bumpy like a lizard skin. I used an automotive product called LizardSkin. I used it on the inside of the Autoexe and the inside of my intercooler box. It quieted both down decently.

Just heard back from Nengun and RHDJapan.
The "HG" kits like we are used to seeing are no longer produced. Instead of a nice mirror finish and cast end tanks, they are now welded and look very different. Entry angle of the pipes is different as well, it's not just cosmetic.
There isn't a new part number, it is just a replacement. Cutting costs most likely.
If you have ordered this kit, go ask RHDJapan and Nengun, hell ask Greddy directly if you have a contact for them, I failed in trying to contact them directly.
I'm fairly upset it's been discontinued and silently replaced with a worse quality kit. Considering cancelling my order.
IRP still has the old style kits listed on his site, maybe he knows more about it?
These are clearly different products, but one is silently replacing the other without a part number change. Just a massive downgrade.

And to add, I'm not even sure it's the same Spec R intercooler core. Waiting to hear back if it's more than just the end tanks that were changed. Considering it looks like a cost cutting move, and the Spec R cores are their most expensive core, I don't have high hopes.
This sucks, this was the best V Mount available. Not sure what the other options are. I might just buy a bare core from Plazmaman and have tanks made to suit my setup.

Also, I don't mean to derail this thread, but I hope the "vmount plug-in play" A/C kit that jp3 is producing doesn't get effected with this new change.

Top 2 pictures are the old style, bottom 2 are the replacement. Visible welds vs cast and polished. Soft smooth entry angle of the charge pipe, vs sharp and welded on.
