I am struggling to choose between racing beat intake or aem intake.
Currently, there is someone selling a racing beat revi for $300 with 2k miles on it.
But, I always wanted the AEM (usually $400-$500) bc I see it everywhere.
But, what is the better choice, I need help deciding which is better for the price and performance.
It will be my first mod and going to get a mid-pipe and cat-back right after.

Both produce the same power improvement - about 1 hp. So it's really down to which looks better to you for the price.

I actually cant really feel the difference between the revi, AEM, or stock.

I like the revi because it’s quieter than the AEM. And they might have a bit more bottom end throttle response…. But really it’s super close to stock. After having both I like them each for different reasons. AEM because it frees up engine bay space. The Revi because it is quieter.. both are super easy to install.

And to not really help you at all.. or maybe this does. The best upgrade for satisfaction I’ve done on any of my rx8’s is the revi cat back exhaust.

if you’re going to spend money.. that should be your first modification.

My car setups in relation to intake and exhaust:

1st: aem intake, duel res midpipe, revi cat back. (With duel Rez midpipe sounds like there is a cat, hear intake over exhaust, intake is loud)

2nd: revi intake (quiet but louder than stock)

3rd: revi cat back (get the most enjoyment from this setup)


When I can I’ll be buying the revi exhaust for car #2. I have an AEM that might go on car #3… but I’m still undecided on that.

Used revis are jumping up in price. Sold mine for 250 euros, now used revis are being sold for 400-450 euros... Personally, I'd try a diy cai in the style of aem or a short style cai to free more space in the engine bay.

As per most legal intake and exhaust modifications it is all about looks and the sound. Whatever you choose it won't improve performance but will sound faster!. Use the money to get better tyres and suspension to improve point to point performance.

Air intake hp/$ for our cars is laughable. The only tangible advantage is an emptier engine bay. You can always eat less cheeseburgers to gain that 1 or 2 hp.

Has anyone who has installed a Revi run into issues with an aftermarket aluminum radiator top tank riding up too high to allow the intake snout of the Revi to fit through the pass through in the forward firewall? If so, how did you get your radiator to play nice and let you go forward. Racing Beat's proposed solution is to sell me a Koyo radiator, which seems to be closer to the OEM radiator's top contour; but it took them 6 months to ship me my Revi, so I'm a bit pessimistic about that option, not to mention not wanting to spend the extra $300+ for the Koyo if I can make my Champion radiator cooperate.I've been searching the forum since yesterday afternoon when I realized my radiator's top tank is in the way. If someone knows of either a troubleshooting or DIY article about how to solve this, and wouldn't mind letting me know where it is, I'd very much appreciate it. I'm going to continue to search for a solution; but I wanted to put my request here in the hope that someone who has installed a Revi and ran into this issue either recalls how they addressed it, or might even have some pics of what they needed to change.

I tttthink I had to grind a couple of mm off the Revi with the CSF rad, but it wasn't a big deal, I don't think it protruded as much as shown here. You could try to shift the radiator lower by bending or shimming its mounts.
