PRL Motorsports RBC Intake Manifold to Stock Throttle Body Adapter Honda Civic Si 2012-2015
$89.99

Hey fellow car enthusiasts! If you’re looking to boost your K-Series engine’s performance, you’ve probably heard about the RRC and RBC intake manifolds. These bad boys are some of the best flowing options Honda has to offer, and they’re a popular swap for those of us dealing with the stock manifolds on models like the 2012-2015 Honda Civic Si or the 2009-2014 Acura TSX. Trust me, if you’re still rocking that less-than-stellar factory setup, this is a game changer.

Now, here’s where it gets interesting. When you’re swapping to an RBC or RRC manifold, you often need a throttle body adapter to make everything play nice together. That’s where our PRL Motorsports Billet Throttle Body Adapter comes into the picture. It’s machined from solid 6061 aluminum, and it fits like a glove, allowing you to adapt your specific DBW (drive-by-wire) throttle body seamlessly to the new intake manifold.

This adapter isn’t just about looks; it’s practical too. It features an O-ring that seals tightly against both the intake manifold and the throttle body, ensuring no air leaks. Plus, it comes with a 1/8" NPT port and a 90-degree fitting, which keeps your factory EVAP Purge system intact if you want it. But if you’re all about that clean engine bay look, you can easily plug it or delete it altogether with a tuner like Hondata FlashPro or KTuner.

Here’s what you get in the kit:

  • (1) PRL Motorsports Anodized Throttle Body Adapter
  • (1) Size 152 O-Ring
  • (1) Size 147 O-Ring
  • (1) 90 Degree EVAP Fitting
  • (4) M8 x 70mm Flange Bolts

Fitment:

  • Honda Civic Si 2012-2015

Note:

  • Works with all variant models including 6MT, RHD, International Models, etc.

So if you’re ready to ditch that stock manifold and make a solid upgrade, this throttle body adapter is a must-have for your setup. It’s straightforward, reliable, and designed for those who want to get the most out of their K-Series engine. Happy modding!
