Unlock Peak Performance for Your K20Z3 Engine

The Skunk2 Pro Series Intake Manifold is specifically engineered to elevate the power output of 2006-2011 Honda Civic Si (K20Z3) and 2004-2008 Acura TSX models. Skunk2 engineers meticulously re-evaluated the popular '06-'11 Civic Si RBC manifold, developing a superior design that delivers significant horsepower and torque gains across the entire RPM range.

Advanced Design for Unrivaled Airflow

This Pro Series manifold features larger plenums and shorter, oversized runners compared to the OEM RBC unit. This optimized geometry dramatically improves airflow and enhances the venturi effect, resulting in a noticeable boost in both mid-range performance and top-end power. Constructed with thicker wall material, the manifold also provides ample opportunity for further porting, making it an ideal choice for high-horsepower, race-only applications.

  • Optimized for K20Z3 engines (2006-2011 Civic Si, 2004-2008 TSX)
  • Larger plenum and shorter, oversized runners for superior airflow
  • Significant gains in mid-range and top-end horsepower
  • Thicker wall casting allows for custom porting
  • Designed for serious street enthusiasts and competitive racing

Experience sharper throttle response and a more aggressive power delivery with this race-proven intake manifold. Skunk2's dedication to engineering excellence ensures your K20Z3 engine performs at its absolute best. Discover this essential upgrade at GGCRACING.
