Radium - Fuel Rail for Honda S2000 (00-05 F20C / F22C)

The Radium Engineering High-Flow Fuel Rail for Honda S2000 (2000–2005 F20C / F22C) replaces the restrictive factory fuel rail on cable-throttle AP1 and early AP2 platforms. Designed with a massive 0.69" internal bore, this CNC machined billet aluminum fuel rail dampens hydraulic injector pulses and delivers uniform fuel volume across all four cylinders under extreme boost.

Key Performance Features:

• Large Internal Bore (0.69"): Provides ample fuel dampening volume to eliminate pressure drops between injection events, supporting over 1,000+ HP builds.
• 8AN ORB Porting: Threaded with 8AN ORB end ports and a center top port for convenient fuel pulse damper or gauge installation.
• OEM Line Integration Option: Available as a standalone rail or bundled with pre-crimped PTFE feed and return hoses that connect directly to factory hardlines.
• E85 / Ethanol Compatible: Hard anodized inside and out for impervious resistance against corrosive alcohol fuels.
• Direct Bolt-On Fitment: Bolts directly to the OEM intake manifold utilizing included stainless steel hardware and phenolic mounting spacers.

Vehicle & Engine Compatibility:

• 2000–2003 Honda S2000 (AP1) - 2.0L F20C
• 2004–2005 Honda S2000 (AP2) - 2.2L F22C1 (Cable Throttle)

Notice: Inlet and outlet ports are female ORB; male AN adapter fittings and hose ends are sold separately unless selecting the OEM Plumbing Kit option.
