Hybrid Racing Fuel Rail for 06-11 Civic Si/04-08 TSX

Hybrid Racing Fuel Rail for 06-11 Civic Si and 04-08 TSX

Give your K-series the steady fuel supply it deserves and a show-quality engine bay at the same time. The Hybrid Racing fuel rail for 06-11 Civic Si and 04-08 TSX is CNC-machined from 6061-T6 aluminum, then hard-anodized in Dust Black or Dust Red for lasting protection against heat, ethanol blends, and under-hood chemicals. A crisp laser-etched Hybrid Racing logo finishes the look, letting everyone know you run the parts real racers trust.

Built for Serious Flow

• Full-bore passage and -8 ORB ports support either -6AN or -8AN lines, eliminating the restriction of the factory rail and future-proofing your build for turbo, supercharger, or high-horsepower N/A setups.
• E85-ready construction and Viton O-rings stand up to today’s corrosive fuels so you can switch blends without swapping parts.

Ready for Clean Gauge Placement

An integrated 1/8" NPT port lets you bolt a fuel-pressure gauge directly to the rail—no adapters, no hunting for space behind the manifold. Keep an eye on vitals at a glance while cleaning up the clutter.

Wire-Tuck Friendly Layout

Prefer a center feed? Simply plug the side inlet/outlet and route your hose to the middle -8 ORB port that slots neatly between cylinders 2 and 3 (PRB, RBC, RBB, and most aftermarket manifolds). The result is a smoother, less crowded engine bay that showcases your K-series instead of hiding it behind hoses.

Direct Bolt-On Fit

Designed around OEM mounting bosses, this rail drops onto the K20Z3 Civic Si and K24A2 TSX manifolds—no spacers, no grinding. Pair it with your favorite injectors and line kit and go.
