Billet Fuel Rail Kit - Mitsubishi EVO 4-9 4G63
 
Extruded rails are the industry's version of "good enough." This isn't that.
 
The Ichiban Engineering 4G63 billet fuel rail is precision-machined from solid 6061-T6 aluminum - not extruded like most of what's on the market. That difference shows up exactly where it matters: flow consistency, sealing integrity, and durability under sustained high-boost pressure.
 
Dual ports support either -8AN or -6AN fittings, so you're not locked into one fuel line configuration. Choose between 11mm or 14mm injector bores for a precise fit with OEM or aftermarket injectors - no forcing the wrong size to make it work.
 
Designed as a direct bolt-on for both OEM and aftermarket intake manifolds, this rail delivers precise fitment across the full EVO 4-9 (4G63) range. Each unit is anodized in multiple colors - black, red, blue, silver, and more - for corrosion protection and a finish that actually looks like it belongs under the hood.
 
Street EVO 8, full-race EVO 9, or a custom 4G63 build outside either category - this rail holds consistent pressure and smooth delivery regardless of which one you're running.
