K-Tuned K-Series Fuel Rail Black TSX 04-08 K24A2 RSX 02-06 Civic Si 02-15 K20A2 A3 K20Z1 Z3 K24Z7

Built from 6061 billet aluminum and fully anodized in aggressive black, this K-Tuned fuel rail transforms your K-series engine bay into a showcase of precision engineering. The versatile three-port design lets you run a center-feed setup for that clean, tucked aesthetic on stock and naturally aspirated builds, or configure dual feeds with a center return for serious boosted applications pushing over 1000 whp. CNC-machined to perfection with a 17.9mm bore, this rail flows fuel exactly where it needs to go without compromise.

The rail fits seamlessly with factory K-series hardlines and accepts both stock and aftermarket injectors with ease. It comes complete with mounting bolts, 8AN port plug, and 6AN and EFI fittings, so you're ready to plumb everything in right out of the box. Whether you're building a stealth street machine or a high-horsepower track monster, the engineering and looks speak for themselves.

If you're serious about K-series performance and refuse to settle for mediocre fuel delivery, this is the rail that belongs in your build.
