Fuel Injector Clinic Four Cylinder 1650cc SHORT Custom Injector Set - 38mm Height - 11mm Top O-Ring Diameter - 14mm Bottom O-Ring Diameter (ISC-1650H-4)
The Fuel Injector Clinic 1650cc SHORT Custom Injector Set is designed for custom four-cylinder performance applications requiring a compact 38mm injector height, 11mm top O-ring diameter, and 14mm bottom O-ring diameter. This short-body high impedance injector is ideal for custom intake manifolds, tight engine bays, and specialized fuel system configurations where standard-length injectors will not fit. Delivering 1650cc/min of fuel flow, these injectors provide the fuel capacity needed for serious turbocharged, supercharged, and naturally aspirated performance builds while maintaining excellent idle quality and drivability when professionally tuned.
Each injector is individually serial numbered and precisely matched using Fuel Injector Clinic's proprietary Data Match Technology, ensuring exceptional cylinder-to-cylinder consistency along with detailed latency data for accurate ECU calibration. Every custom injector set includes solder-in pigtails, the required O-rings for the specified dimensions, and a comprehensive Data Match Sheet. Each injector is flow tested at 43.5 PSI (3 Bar) at 90 degrees F using CF-16B calibration fluid and is backed by Fuel Injector Clinic's lifetime warranty against manufacturing defects.

This injector set is intended for custom applications and is not vehicle specific. Compatibility is determined by injector height, O-ring dimensions, fuel rail, intake manifold, electrical connector, and engine management system. Verify all measurements before ordering. If you are using an aftermarket or specialized fuel system configuration, contact Beefcake Racing before placing your order to ensure you receive the correct injector setup.
FAQs
Why would I choose the SHORT 38mm injector version?
The 38mm SHORT injector is designed for custom applications where engine bay or intake manifold clearance prevents the use of standard-length injectors. Always verify your injector height requirements before ordering.
What does Fuel Injector Clinic's Data Match Technology provide?
Each injector is individually flow tested, serial numbered, and matched before shipment. The included Data Match Sheet contains detailed flow and latency information, allowing tuners to achieve more precise ECU calibration and consistent fuel delivery across every cylinder.
