I know this intake is OLD news, but i've seen few if any tests that presented data. i decided to try it out for myself. I think all of racing beat's claims for this intake are pretty fair. small bump in power, nice fitment, and minimal impact to noise. a nice OEM+ upgrade!
It's cool but I am happy with my AEM CAI as it cleans up the engine bay nicely. It's that much easier to work on the car and the intake noise paired up with my full racing beat exhaust note is awesome WOT! = )
Its hard to beat the stock intake, I mean the racingbeat REVI could just be seeing a benefit from a different filter material and that is the power bump. The stock intake already gets cold air from infront of the front wall. The REVI scoop may get slightly higher pressure air from your ram speed compared to the stock which pulls air pressure from inside your wheel wells and pre radiator pressure, but I doubt its much of a difference considering they never showed any measurements for it. The BIG downsides with the REVI and the AEM style intakes are that they place the filter or scoop in a water prone location which isn't great for a daily driver longterm.
You can also make your own intake fairly easily with tubes and picking out a large filter that can sit up inside the bumper where the VFAD is located. Just make sure the MAF housing is located properly and is the appropriate inner diameter for consistent data. Its just tricky to put mesh in there to give the maf laminar airflow without having a ton of silicone joiners.

I've used the AEM on and off at different times on both my white and blue RX-8s. it's a nice piece that flows well and definitely frees up engine bay space. i was looking for a more mature intake sound... the AEM attracts a LOT of attention!

I would rather something weldable if that. You definitely don't want to suck something down your intake by accident whether its the comb or a blob of epoxy that lets go of the aluminum next time winter hits. Cool find though, welding may be tough.

True for the AEM but the Revi still has the filter element further down the intake tract, suspended in a box. The chances of soaking the filter and ingesting water are pretty low.

This air straightener is what I used on my REVi intake when my OEM screen tore. With light trimming the interference fit is perfect into the end of the velocity stack or horn. Immediately after that I placed a 1/8" aluminum ring, 3.5" OD x 3.14" ID, sourced from eBay. The lip is just enough to provide further reassurance the air straightener can't slip into the MAF tube and toward the TB. Maybe it affects flow and turbulence, but it evened out my idle, and that's all I really cared about.

I highly doubt you would suck up water the way the filter and intake is designed. It's a good design IMO how it sits sideways and high enough to not worry about ingesting water. I can see that maybe on the Honda intakes I've seen where space is so limited that the intake has to go as low as by the car undercarriage or by the wheel well which can create a possible submersion in water if the puddle is big enough. Either way, I added the water proof mesh screen and that seems to help keep the filter clean and dry at all times.

My Rx8 already came with the AEM intake installed. I think if I was starting from scratch - I would have simply done a drop in K&N filter. I agree that Mazda did a good job engineering the stock intake as I've seen the setup when I go to the junk yard for parts. The intake basically takes in cooler and more dense air in how it's routed. I have also seen the short ram (hot air) intakes and always thought they were a waste of money. You basically go from cooler air to the hot air from the under the hood heat.

I made my own intake for way less, I used the honeycomb type you posted. I just carefully drilled 1/8 holes (rivots) just inside the neck of my treadstone maf setup, it already has a slight lip on the inside and it’s not going anywhere in front of the maf. I don’t like my longer 6” coupler in front, I just installed the autoexe so that changed everything. that’s not staying as I just needed something until I add on or get a longer 90 degree pipe for the front.
