The Wagner Tuning Toyota Supra GR (MK5) B58 Fuel Rail Fitting Kit (Fittings Only) is a high-flow fuel delivery component designed to support elevated fuel demand on modified high-output applications. The factory fuel rail and fittings are sized for stock injector flow rates and can become a restriction at higher power levels, causing fuel pressure drop and inconsistent delivery under wide-open throttle. This Wagner unit addresses that limitation with larger internal volume and properly sized port connections.

Direct-fit installation using OEM mounting points. Verify fitment with your specific injector and fuel line configuration before ordering. Includes specified hardware as noted in the product title. Intended for modified applications with increased fuel flow requirements beyond OEM spec.
