Note: Read all instructions before attempting installation.
If you do not believe you are qualified in performing the
necessary installation and/or modifications, please find an
experienced professional who can. Karcepts, Inc. will not be
held responsible for improper modifications to your chassis,
engine, or any other associated parts. It is your job to make
certain adequate clearances are provided to fit an RBC or
RRB intake manifold into your vehicle.

1. PREPARATION
1. emove the EVAP hose, brake booster hose, PCV hose, vacuum hose, water
bypass hoses, throttle cable, fuel lines, fuel injector connectors, IAC valve
connector, TP sensor connector, MAP sensor connector, and EVAP canister
purge valve connector from your current intake manifold and throttle body
setup.
2. emove the throttle body.
3. emove the intake manifold brackets, intake manifold, and intake manifold
gasket.
If adapting an Accord Euro R or 06 Civic Si intake manifold onto an 02-
06 RSX/ITR or 02-0 Civic Si/CTR style head, continue to follow the
remaining “PREPARATION” steps, otherwise skip to “INSTALLATION”.

1. PREPARATION (continued…)
4. Line up a K20A/A2/A3/Z1 intake manifold gasket with the intake ports of the
BC/ B manifold, and mark the manifold for cutting.
5. Use a vice to hold the manifold securely, and cut the majority of the coolant
passage from the manifold with a metal cutting disk.

1. PREPARATION (continued…)
6. To clean up the cut and contour the manifold according to the markings, use a
60 grit flap disk with your grinder.

1. PREPARATION (continued…)
7. Locate the port on your BC/ B manifold flange that stems from the nipple
atop the manifold. Mark and drill a 15/32” hole into the intake manifold gasket
to line up with this port. For ease of drilling and sealing, use a Hondata (or
equivalent) 02-06 K20 intake manifold heat shield type gasket.

2. INSTALLATION
1. Line up the 16176- BC-004 throttle body gasket as shown.
2. With a 6mm Allen Wrench, bolt the adapter onto the intake manifold with four
M8 socket head cap screws.
3. Line up the 16176-P B-A01 throttle body gasket as shown.

2. INSTALLATION (continued…)
4. Bolt your K20A/A2/A3/Z1 throttle body to the adapter with the remaining M8 hex
head cap screws and M8 lock washers.
5. Actuate your K20A/A2/A3/Z1 throttle body by hand and observe if there are any
interferences with the throttle body rotor and the adapter when opening up to
simulate full throttle. If any interferences are observed, loosen the M8 hex head
cap screws and re-position the throttle body (The K20A/A2/A3/Z1 throttle body
has large hole clearances which allow a bit of adjustment if just loosening the
hardware and re-adjusting the throttle body position). If the throttle body bore
is on-center with the adapter bore, you can observe that no interferences will
be seen.

2. INSTALLATION (continued…)
6. If using a K20A/A2/A3 TB, install a provided rubber plug into your BC/ B
intake manifold MAP sensor port. Use a tool to aid with insertion.
For a K20Z1 TB, relocate the MAP sensor on the TB to the MAP sensor location
on the BC/ B intake manifold. Then use a provided rubber plug to block the
no longer utilized MAP port on the TB.
7. Install the intake manifold and throttle body assembly onto the engine. e-
connect the EVAP hose, brake booster hose, PCV hose, throttle cable, fuel
lines, and electrical connectors.

2. INSTALLATION (continued…)
8. If trying to re-connect the stock water bypass hoses, you may find that they are
too short with the new throttle body position. You can choose to loop the inlet
on the block to eliminate the coolant flow to the throttle body (left image below),
or obtain 5/16” I.D. hose to connect the system in stock fashion (right image
below).
9. If using a 02-06 SX/IT or 02-05 Civic Si/CT style head, install the 36283-
AA-A00 vacuum hose from the nipple on top of the intake manifold to the
intake air bypass control thermal valve.

3. FINAL CHECKS/CLEARANCES
Because of the larger intake manifold being utilized, even in a confirmed vehicle,
there are some close interferences where precautions may need to be made. The
two major concerns are shown below. The IAC valve and TP sensor connector will
get close to the radiator and upper radiator hose. Depending on the type of
radiator, radiator fan, radiator placement, and upper radiator hose being used,
there may be a possible interference concern in this area. Additionally, the EVAP
canister purge valve atop the K20A/A2/A3/Z1 throttle body may prohibit closure of
some hoods. It may be a requirement to bend in or cut a small piece out of the
inner skeleton in order to close the hood on your vehicle. Another option is to
completely remove the EVAP valve altogether (an additional rubber plug is
provided to plug the unused port with EVAP valve removal). It will be at the sole
discretion of the installer to resolve any potential issues in these areas.
With regards to a 2002-2006 Acura SX-S/Honda IT , the above mentioned issues
will be of no concern; however, reconfiguration of the stock AC brackets will be
required (as shown below). Additionally, the hood stay holder will need to be
removed/modified on that chassis.
Note: An SX-S Injen CAI will mount directly up to a 2002-2006 Acura SX-
S/Honda IT utilizing an BC/ B intake manifold and this adapter.

CONGRATULATIONS! YOUR RBC/RRB/RBB
INSTALLATION SHOULD NOW BE CO PLETE!!!
