OEM HONDA CIVIC SI RBC INTAKE MANIFOLD
The dyno graph above shows the difference in power gains. The red line is the RBC manifold and blue is the PRB manifold. As you can see, the PRB makes power to 7400rpm before falling off and the RBC keeps making power all the way to redline. All testing was done on an 06' RSX-S with a DC Sports Header and Cold Air Intake.
MUST BE MODIFIED to fit K20A/A2/A3/Z1 & K24A1 cylinder head
