4G63 Billet Fuel Rail + Injectors - Set

Stop matching parts across two different listings. Get both, matched, in one box.

Buying a fuel rail and injectors separately means hoping the color matches, hoping the fitment lines up, and placing two orders instead of one. The Ichiban Engineering 4G63 fuel rail and injectors set eliminates all of that - our in-house CNC billet fuel rail and Bosch-based injectors, bundled together and guaranteed to work as a system.

Base price includes the billet fuel rail in your choice of color, paired with our flow-matched 1000cc injectors - good for 450whp on E85, higher still on 91/95/100 octane pump gas before you're maxing out the injectors. Need more flow? Step up to 1300cc, 1600cc, or 2200cc from the dropdown, all flow matched to the same standard.

Every injector is tested static and dynamic on our in-house ASNU system, with a flow data sheet included so your tuner starts with real numbers, not guesses. Top hats are CNC machined from billet aluminum in-house, available in multiple anodized colors to match the rail.

Buying the set instead of separately saves you real money over ordering the rail and injectors individually - one order, one shipment, guaranteed compatibility.
