Proflow's billet fuel rail kits fit like stock, but deliver the increased fuel volume that your car needs for maximum performance. The 17.5mm bore rails are precision CNC-machined from high-strength AL6061-T6 aluminium with a polished-anodised finish, allowing them to be used wth all popular alcohol blends such as E85. This kit also include fittings with Viton® O-rings for a superior seal, billet mounting brackets, and stainless steel hardware. 

Suits a standard full length 14mm injector, while injector adapters can be used if using short or 3/4 length injectors.
