Honda RBC Intake Manifold 17100-RRB-A00

Honda RBC Intake Manifold - 17100-RRB-A00

The RBC is the intake manifold the K-series world runs, and it's earned that reputation honestly. Honda put it on the 2006-2011 Civic Si, and builders have been swapping it onto everything since, because it flows better up top than the manifolds it replaces and it keeps pulling all the way to redline. If your build lives above 7,000 RPM, this is one of the cheapest real power gains available to you. It's genuine Honda, part number 17100-RRB-A00, with all the fitment and reliability that comes with an OEM part.

Why The RBC Beats The PRB And PRC

Here's what actually changes. Compared to the factory PRB and PRC intake manifolds, the RBC flows more air past about 5,500 RPM and carries that advantage right to redline. Below that you're not giving anything up worth worrying about, and above it the difference is real. That's why it's the default choice for high-compression builds, cammed engines, and turbo K-series setups where the top of the rev range is where you're living. It's also why you see them on so many K-swapped chassis and race cars, it's OEM hardware doing a job most aftermarket parts charge a lot more to do.

Fits The K24A Engines Directly

The RBC bolts straight onto the K24A family, which is why it's such a popular upgrade for those cars:

• 2006-2011 Honda Civic Si
• 2004-2008 Acura TSX (K24A2)
• 2003-2007 Honda Accord (K24A4, K24A8)
• 2003-2011 Honda Element (K24A4, K24A8)

K20 Heads Need One Modification

The RBC also works on K20 cylinder heads, but there's a step involved. You'll need to cut off the integrated coolant ports so the manifold clears the head's water neck. That sounds worse than it is, it's standard practice at this point and thoroughly documented across the K-swap community, but go in knowing it's part of the job rather than discovering it with the manifold in your hands.

• 2002-2006 Acura RSX (K20A2, K20A3, K20Z1) - requires coolant port modification
• 2002-2005 Honda Civic Si, EP3 (K20A3) - requires coolant port modification
• 2002-2006 Honda CR-V (K20A4, K24A1) - requires coolant port modification

Now Fits K24Z Engines With The PRL Adapter

Good news if you're in a newer K24Z car. The RBC doesn't bolt to a K24Z head on its own, but with the PRL K24Z RBC Intake Manifold Adapter it does, which opens this manifold up to a whole group of cars that couldn't run it before. The adapter mates the RBC to the K24Z2, K24Z3, and K24Z7, covering:

• 2012-2015 Honda Civic Si (K24Z7)
• 2013-2015 Acura ILX (K24Z7)
• 2009-2014 Acura TSX (K24Z3)
• 2008-2012 Honda Accord (K24Z2, K24Z3)

So if you've been watching K24A guys run RBC manifolds and figuring you were stuck, you're not. Grab the adapter alongside this manifold and you're in.

Running A 75mm Throttle Body?

If you've stepped up to a larger throttle body, look at the Hybrid Racing 75mm Ported RBC Intake Manifold instead. It's this same manifold, CNC-machined to open the throttle body flange out to 75mm so it matches up cleanly with the Hybrid Racing RBC Throttle Body (HYB-THB-01-05). Each one is precision machined for a flat, accurate sealing surface and a proper port match, so you're not stepping air across a mismatched flange on its way in.

One honest note on that option: the porting is on the throttle body surface only. It does not port the manifold where it mates to the cylinder head.

Why People Keep Buying The RBC

• Proven high-RPM power gains over the PRB and PRC manifolds
• Ideal for high-compression, cammed, or turbocharged K-series builds
• Genuine Honda part, so factory fitment and factory reliability
• The go-to manifold for K-swapped chassis and race cars

Who Should Run This Manifold

This is for anyone building a K-series that spends real time at high RPM, whether that's a street car you've cammed up, a turbo build, or a race car chasing every last bit at the top end. It's Honda engineering with a long track record behind it, and it's still one of the best value upgrades in the K world. Check whether your engine needs the coolant port modification or the PRL adapter, order accordingly, and bolt it on.
