HARDmotion Ultimate 2012-2015 Honda Civic Si RBC Intake Manifold Adapter kit

The HARDmotion Ultimate 2012-2015 Honda Civic Si RBC Intake Manifold Adapter kit. This kit includes everything you need or ever want all in one place, has every variation from mild to wild and is built to be a bolt-on application which, comes with all needed adapters. Helps with upper power gains as well as turbo applications. There are a few different options here from simple to more performance based. If you have any questions feel free to shoot us an email.

Running Stock Throttle Body: Can be done, you will need either our special gasket or will need to close the ivac hole yourself, hint: just get our gasket.
Also need shorter bolts (Needed 2 packs) M8-1.25 X 50mm. Or you can match the stock throttle body with the prl adapter which is more expensive.

J35 or ZDX Throttle Body: The J35 is a larger than stock throttle body, this will allow more air flow. The ZDX is even larger and requires an adapter. We will supply all that.

K-Tuned Adapter & Bypass: If using the K-Tuned adapter and bypass you get the best of both worlds of the adapter for the coolant line to allow you to fit the RBC manifold and the bypass of the hot coolant from the intake manifold. This is the best bang for your buck performance upgrade, only drawback is you have to cut your RBC to install.

PRL Manifold Adapter: This allows you to not cut anything, its more pricey and more bulky and adds volume to the RBC Intake Manifold. The K-tuned is cleaner and performs better due to bypass.

Intake: You can use the Skunk2 9th Gen RBC Adapter + Skunk2 9th Intake, Hybrid Racing 8th Gen, PRL RBC Short Ram or PRL Cold Air Intake. We recommend the Hybrid Racing Intake.

Intake Manifold Gasket: The intake manifold gasket is a thermal gasket which prevents heat from getting into the intake and raising temperatures. If you use this you will need to relocate your ground wires to the head. This is very important or you will have voltage issues and can hurt your ecu or flashpro. Please check diy's on how to do this.

Overview:

- OEM Honda RBC Manifold is included
- Adapter for the RBC to fit 12-15 Civic Si & Throttle Body (k24z7 motor) or K-Tuned Adapter (you have to cut manifold)
- Injector Adapters (to fit your stock injectors) or upgraded injectors from RDX 410CC up to 1500CC injectors which fit the rbc without the inlet adapter.
- Use Stock Throttle body (needs gasket) J35 Throttle Body or ZDX Throttle Body Upgrade (omits need for throttle body adapter for stock throttle body)
- Build time can be anywhere from 1-3 weeks.

Requires: (please read)
- Needs Flashpro & a tune or basemap
- Needs a Properly routed RBC Intake or RBC coupler to adapter your intake, you can also use 06-11 civic si intakes (not perfect fit but close)
- Competent installer and understanding of what parts are being ordered. We have tried our best to explain everything and direct you to the proper setup, but please do research beforehand too.
- Aftermarket and RDX Injectors may need wiring / adapting to stock harness (please take note of this).

    These guys really put together an awesome setup. I had a few questions they answered it and boom was at my doorstep very quickly considering all the pieces that had to come together. The port work is amazing!
