Injector Dynamics ID1050x USCAR 60mm Height 14mm purple adaptor top 14mm lower o-ring Injector Set of 4 For BMW M3 E30 88-91 Ford Focus RS Nissan S13 S14 S15 & Toyota Celica All-Trac (1050.60.14.14.4)

The Injector Dynamics ID1050x is a motorsport-specification high-flow fuel injector developed through the partnership between Injector Dynamics and Bosch Motorsport. This set of four injectors features a 60mm overall configuration, USCAR electrical connector, 14mm purple adaptor top and 14mm lower O-ring, making it suitable for a range of performance applications including selected BMW, Ford, Nissan and Toyota models.

Developed as the evolution of the highly regarded ID1000, the ID1050x incorporates technology and development experience gained from the larger ID1300x and ID1700x injectors. Rather than being a modified standard production injector, the ID1050x is manufactured specifically as a motorsport injector, with critical operating characteristics optimised for performance engine management and accurate tuning. Its improved internal flow path provides approximately 5% greater output than the original ID1000 while retaining excellent low-flow performance.

With a nominal flow rate of 1065cc/min at 3.0 Bar (43.5psi) and stable operation at differential fuel pressures up to 10 Bar (145psi), the ID1050x is suitable for a wide variety of naturally aspirated, turbocharged and supercharged builds. Corrosion-resistant internals provide compatibility with all known fuels, while a replaceable inlet filter helps extend service life. Available as a matched set of four from JDM Part Shop, ideal for serious performance and motorsport fuel systems.

Fitment depends on the engine, fuel rail, manifold and electrical connector configuration. Modified vehicles may use aftermarket fuel rails with different injector requirements, so dimensions should always be checked before ordering.

Accurate Injector Data

One of the major advantages of Injector Dynamics injectors is the availability of detailed injector characterization data for compatible engine management systems.

Accurate injector data is critical when calibrating an ECU. Injector flow characteristics, dead times and other compensation data allow the ECU to calculate fuel delivery more accurately across different operating voltages, pressures and conditions.

Injector Dynamics provides detailed characterization data for its injectors, helping professional tuners achieve improved fuelling accuracy, idle quality, drivability and calibration consistency rather than relying on generic injector values.

Fuel Compatibility

The ID1050x features corrosion-resistant internal components and is designed for use with all known automotive fuels. This makes it particularly suitable for performance vehicles using alternative or corrosive fuels where injector durability is an important consideration.

Correct fuel system compatibility should still be confirmed for the remaining components in the vehicle, including pumps, hoses, filters, regulators and fuel rails.

Important Installation & Tuning Information

These are high-flow performance fuel injectors and ECU calibration is required after installation. Do not install larger injectors without ensuring that the engine management system is correctly configured for their characteristics.

Injector fitment should also be confirmed using the physical dimensions and O-ring sizes rather than vehicle model alone, particularly on modified vehicles where the original fuel rail or intake system may have been changed.
