This is for a NEW unmodified OEM Honda 2006-2011 Honda Civic Si RBC intake manifold.
The best bang for your buck K-series intake manifold. Proven for many years in stock trim or ported to stand against many “RACE” manifolds.
- Provides mid to high end hp gains.
- Will require coolant passage to be cut off/modified to bolt on for K20A2/Z1 cylinder heads
- These manifolds make huge gains over stock RSX/TSX style intake manifolds
- Throttle body adapter will be required to run wire driven throttle bodies from K-Tuned or Karcepts
- Coolant passage adapter required to run on K20 cylinder heads like this from K-Tuned after coolant passage has been modified on intake manifold.
- 2012-2015 Civic Si owners will need to purchase PRL Motorsports RBC manifold adaptor and RBC Injector adaptors to run this manifold
- K20 Cylinder head owners will find this Hondata K20 thermal intake gasket easy to install along with being a template to cut off the coolant passage
- K24A cylinder heads can use this Hondata K24A thermal gasket for direct installation!
- As always with installation we always recommend tuning software to maximize gains from this Intake manifold swap
