Revo-tune
 

Revoution Throttle Body sorry for google translate
It is an electronic throttle kit 70Φ.
Is the inner diameter of genuine respect 70Φ 65Φ.
Can be mounted on the bolt, so I also optimized for 86/BRZ throttle body, it is available in both normal ECU · tuned ECU.
Because the products are not genuine processing, eliminating the need for trade-in. ※ suction pipe there may be other third-party, not with the combination. ※ adapter is anodized red.
Tax-included price : ¥ 52,500


Carbon air cleaner suction kit
Tax-included price : 168,000 yen

I'd love to see some independent graphs of these parts. I've wondered about a throttle body spacer several times but don't have access to a lathe anymore. And that intake looks like it migh have a chance of being more efficient.

do I hear $1,500-ish for an intake?

You mean $2,100-ish?

Throttle body spacer? What exactly is that supposed to do on a port/direct injected engine?

The only thing it could do is increase plenum volume. There's a lot of theories on how to size the plenum to get maximum performance but I'm hypothesizing that a larger plenum would help top end power without adversely effecting power anywhere else. It could possibly help power everywhere. There might be a decrease in throttle response though as engine power doesn't change until the air pressure in the plenum changes. It's all give and take. Honestly I doubt a change in volume as small as a throttle spacer would be noticeable, but I'd love to see the research to find out.

Now THAT! is an Intake! Reminds me of the Varram intakes we install on all the camaros and TZ
