The Focus RS Inline-5 Engine:\u003c\/h4\u003e\n\u003cp\u003eThe Ford Focus RS MK II through MK IV uses a 2.5-litre turbocharged inline-5 cylinder engine (Duratec RS), which is why this injector set contains 5 injectors rather than the more common 4 or 6. The inline-5 configuration is one of the defining characteristics of the Focus RS, producing a distinctive exhaust note and strong power output. When upgrading injectors on the Focus RS, it's critical to order the correct quantity of 5 to replace all cylinders simultaneously for consistent fuel delivery across all cylinders.\u003c\/p\u003e\n\u003ch4\u003eID1300x - High Flow Performance Injector:\u003c\/h4\u003e\n\u003cp\u003eThe ID1300x is Injector Dynamics' high-flow injector designed for serious performance applications. At 1340cc\/min (approximately 127 lb\/hr) at 3 bar, these injectors can support substantial power levels on gasoline or E85. The \"x\" designation indicates the advanced disc-style internals that provide superior linearity and low-pulse-width performance compared to ball-and-seat designs. This means the injectors perform accurately across the entire duty cycle range, from idle to wide-open throttle, enabling precise fuel control at all operating conditions.\u003c\/p\u003e\n\u003ch4\u003eCharacterization Data - The Injector Dynamics Advantage:\u003c\/h4\u003e\n\u003cp\u003eEvery set of Injector Dynamics injectors comes with comprehensive characterization data that describes the injector's precise flow behavior across different pulse widths, fuel pressures, and temperatures. This data is used by your tuner in the ECU to accurately model fuel delivery, enabling a more precise and efficient tune. Without accurate characterization data, tuners must estimate injector behavior, which can result in a less accurate tune. The Injector Dynamics characterization data is recognized and supported by all major ECU platforms including Haltech, Link, AEM, Motec, and others.\u003c\/p\u003e\n\u003ch4\u003eE85 and Ethanol Compatibility:\u003c\/h4\u003e\n\u003cp\u003eThe ID1300x injectors are fully compatible with E85 and other ethanol blends. The internal components and seals are resistant to ethanol's corrosive properties, ensuring long service life even with sustained E85 use. E85 requires approximately 30-40% more fuel volume than gasoline due to its lower energy density, making high-flow injectors like the ID1300x essential for E85 Focus RS builds. The 1340cc flow rate provides ample capacity for high-power E85 applications on the Focus RS's 2.5T engine.\u003c\/p\u003e\n\u003ch4\u003e60mm Body Length - Dimensional Verification:\u003c\/h4\u003e\n\u003cp\u003eThe 60mm body length, 14mm top O-ring, and 14mm lower O-ring dimensions must match your Focus RS fuel rail for proper fitment. These dimensions are specific to the Focus RS MK II-IV fuel rail configuration. Always verify your fuel rail's injector pocket dimensions before ordering. Using injectors with incorrect dimensions can result in fuel leaks or improper seating. If you are unsure of your fuel rail's specifications, consult your engine builder or tuner.\u003c\/p\u003e\n\u003ch4\u003eFuel System Requirements:\u003c\/h4\u003e\n\u003cp\u003eInstalling 1340cc injectors on the Focus RS typically requires a fuel system capable of supplying adequate fuel volume and pressure. At high duty cycles, 5x 1340cc injectors can demand significant fuel flow. Ensure your fuel pump, fuel lines, and fuel pressure regulator are capable of supporting the injectors' maximum flow requirements. An upgraded fuel pump is commonly required alongside high-flow injectors on the Focus RS platform. Your tuner can advise on fuel system requirements based on your target power level and fuel type.\u003c\/p\u003e\n\u003ch4\u003eWhy Injector Dynamics?\u003c\/h4\u003e\n\u003cp\u003eInjector Dynamics is the industry standard for high-performance fuel injectors, trusted by professional engine builders, race teams, and tuners worldwide. Their commitment to providing accurate characterization data sets them apart from competitors, enabling more precise and reliable tunes. Injector Dynamics injectors are used in championship-winning race cars and high-power street builds worldwide.\u003c\/p\u003e\n\u003ch4\u003ePerfect For:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eFord Focus RS MK II, MK III, and MK IV high-power builds\u003c\/li\u003e\n\u003cli\u003eE85 Focus RS builds needing high-flow ethanol-compatible injectors\u003c\/li\u003e\n\u003cli\u003eFocus RS builds requiring 1340cc injectors for serious power targets\u003c\/li\u003e\n\u003cli\u003eAny Focus RS application needing accurate characterization data for precise tuning\u003c\/li\u003e\n\u003cli\u003eProfessional builds demanding Injector Dynamics quality on the 2.5T inline-5\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePerfect For:\u003c\/strong\u003e Ford Focus RS MK II-IV owners seeking Injector Dynamics ID1300x injectors for high-flow fuel delivery on gasoline or E85 with accurate characterization data for precise tuning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePro Tip:\u003c\/strong\u003e Provide your tuner with the Injector Dynamics characterization data before your dyno session - it enables a more accurate and efficient tune from the start, especially important on the Focus RS's 5-cylinder engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProfessional Tuning Required:\u003c\/strong\u003e 1340cc\/min @ 3 bar.
