Billet Performance Products 14mm 1/2 to Full Length Fuel Injector Adapter converts compatible short Bosch injectors to a full-length format so they can be used in fuel rail and manifold combinations designed around a taller injector body.It is a practical EFI fuel system solution for custom builds where injector height is the difference between a clean install and a frustrating mismatch. By correcting injector length, it helps make Bosch short injectors easier to package in aftermarket fuel rails while keeping the assembly secure and serviceable.This adapter is especially useful in workshop builds using Bosch 1650cc or 2000cc short injectors, custom rails and fabricated intake setups. It also keeps the parts list simpler when you want to retain a proven injector but need a different installed height.Features Function: Converts 1/2-length injectors to full length Injector fitment: 14mm style adapter Injector compatibility: Bosch 1650cc and 2000cc short injectors Finish: Black anodised Included: Filter basket and injector clip Purpose: Corrects injector height in EFI rail and manifold setups Supplied as: Single adapter Typical Applications Custom EFI fuel system upgrades Bosch short injector conversions into full-length rail packages Street, drag and circuit builds using aftermarket fuel rails Fabricated manifold and rail combinations needing injector height correction Workshop fuel system planning and service Fitment Notes Designed for compatible 14mm Bosch short injectors including 1650cc and 2000cc units Always check injector length, O-ring dimensions and rail/manifold spacing before ordering This part changes installed injector height only and does not alter injector flow or impedance Best suited to custom EFI combinations where a full-length injector format is required
