What to check
- The plenum volume grows with spacers, sold separately, and the runner walls are thick enough for porting.
- It uses the PRB / PRC head and throttle body flange; on RBC / RBB heads it fits with a water bypass adapter and the Skunk2 309-05-0120 throttle body adapter.
- On the 2002-2005 Civic Si (EP3) the radiator core support must be trimmed, and the TPS wiring and upper radiator hose may need changes.
- The plenum rotates, so the throttle body can sit on the driver or passenger side.
- The black version is wrinkle powder coated.
- Skunk2 recommends it for naturally aspirated engines up to 275 hp and turbo or supercharged engines up to 750 hp.
