Group, New to this group. I have searched and was unable to find a thread on whether a RBC intake will fit on a 2012. Any help is greatly appreciated.

AEM Intake, Grams throttle body, AEM Spacer, Hondata Flash Pro. Greddy Exhaust, and skunk2 exhaust manifold.

You'll need a couple of adapters to get the RBC manifold to fit on a 2nd gen TSX. One that'll mount to the intake ports and another for the throttle body. PRL makes them (P/N: PRL-HC9-IM-KIT and PRL-HC9-IM-STK). Not sure if you'll need a new intake pipe if you're running a stock airbox.

Hi all, 2012 TSX owner here with K24Z3 (2 months exactly today). Wondering what advantages this mod does to the K24Z, and do we need to do a tuning after installing RBC manifold?

Thanks in advance.

Without a tune, you’ll lose power in the lower rpms. Not a good mod for a daily. To take advantage of the RBC, you would need at least a CAI + tune, otherwise, you’re better off staying with the stock intake manifold.

One thing I forgot to mention is that the stock 2nd gen TSX injectors will not fit the RBC manifold. You’ll either need to get a set of compatible injectors from a 1st gen TSX, 8th gen Civic si, or upgrade to the RDX injectors. Otherwise you will need to bore out the manifold to make the stock injectors fit. If you go the new injector route, you’ll need another set of adapters to plug into the injectors.

If you don't mind, where would I find the adapter? Is there an injector size you would recommend for a daily? Thanks for the great information

I should have said if I wanted to go aftermarket injector

Heeltoeauto.com is basically your one stop shop for all the parts you’re looking for. Marcus is a great guy and he will be able to tell you all of the parts and adapters needed to get the RBC mani swap done.

Unless you plan to do force induction, after market injectors may be overkill. The factory RDX injectors should be plenty good for what you’re looking for. Keep in mind that you’ll need a Flashpro base map loaded to support the larger injectors. Otherwise your car will either run very rough or not be able to start at all.
