Injector Dynamics 1340cc Injectors - 48mm Length - 14mm Black Bottom - 14mm Lower O-Ring (Set of 4)

Overview

The Injector Dynamics ID1300x² 1340cc Fuel Injector Set (Part #1300.48.14.14B.4) is the ultimate high-flow injector upgrade for performance-minded 4-cylinder enthusiasts targeting big power on E85, methanol, or gasoline. Co-engineered with Bosch Motorsport specifically for the demands of motorsport tuners, this set of four 48mm injectors with 14mm black bottom adapters is engineered to support forced-induction 4-cylinder applications well into the 600–750+ wheel horsepower range. Whether you're building the best high-flow fuel injector setup for a 2008–2015 Mitsubishi Lancer Evolution X or a similarly configured short-body 4-cylinder platform, the ID1300x² delivers race-proven performance with OEM-grade drivability.

Key Features & Benefits

• 1340cc/min Flow Rate @ 43.5 psi — Measured using Iso Octane at 52°C per ISO standards; delivers consistent, validated fuel delivery at the flow levels required for 600–750+ WHP forced-induction builds.
• All Stainless Steel Internals — The ID1300x² is the only high-performance injector on the market built with fully stainless internals, offering unmatched resistance to the corrosive nature of ethanol, methanol, and other alternative fuels for extended service life.
• Compatible With All Known Fuels — Purpose-built for E85, ethanol, methanol, and alternative fuels while retaining full gasoline compatibility — switch back to pump gas without sacrificing idle quality or drivability.
• Dual Slope Matching Technology — Injector Dynamics' proprietary Dual Slope Matching matches injectors across both the linear and non-linear (low pulse width) operating range, delivering the tightest possible cylinder-to-cylinder fuel balance from idle to wide-open throttle.
• Improved Internal Flow Path (+5% Output) — An enhanced flow path increases output by 5% versus the previous generation without compromising low-flow performance, preserving stock-like idle behavior even on small-displacement engines.
• Stronger Magnetic Circuit — Stable to 6 Bar — A reinforced magnetic circuit ensures consistent, reliable operation at elevated fuel pressures up to 6.0 Bar (87.0 psi), critical for boosted and flex-fuel applications.
• Replaceable Inlet Filter — Field-serviceable inlet filter protects the injector internals and extends service life without requiring full injector replacement.
• OEM-Quality Injector Characterization Data Included — Injector Dynamics is the only motorsport injector supplier capable of generating OEM-grade characterization data. Full Dead Time (Latency) and Flow vs. Pressure tables are provided, making ECU calibration faster and more accurate for tuners using platforms such as EcuFlash, AEM, Haltech, Link, MoTeC, and more.
• USCAR (EV6/EV14) Electrical Connector — Modern industry-standard connector ensures broad compatibility and plug-and-play adapter availability for virtually any ECU harness.
• Compact 48mm Body — 200+ Vehicle Fitments — The short 48mm O-ring-to-O-ring body fits over 200 applications, including current and future platforms utilizing short-body injectors, making this one of the most versatile injectors in the ID lineup.

Specifications

Fitment & Compatibility

The 1300.48.14.14B.4 configuration (48mm length, 14mm top bore, 14mm black bottom adapter) is the correct injector set for a wide range of 4-cylinder platforms that use a short-body injector with a 14mm lower adapter interface. This part number is a confirmed fitment for the 2008–2015 Mitsubishi Lancer Evolution X (4B11T) and is also used across numerous other turbocharged 4-cylinder applications that share the 48mm O-ring-to-O-ring specification. With over 200 compatible vehicle applications in the ID1300x² lineup, always cross-reference your specific year/make/model against the official Injector Dynamics Application Guide at injectordynamics.com before purchase to confirm your exact fitment configuration.

Confirmed Primary Fitment:

• 2008–2015 Mitsubishi Lancer Evolution X (4B11T Turbocharged)

Note: Other 4-cylinder applications using 48mm injector length with 14mm upper and 14mm lower O-ring interface may also be compatible. Verify your application via the Injector Dynamics application guide.

Installation

The ID1300x² is a high-impedance (saturated) injector and is compatible with factory ECUs and standalone ECU systems without the need for an external injector resistor box on most modern platforms. For the Mitsubishi Evo X, installation requires USCAR-to-Denso plug-and-play adapters (Injector Dynamics P/N 90.3) and an injector resistor pack delete plug to complete the installation. No fuel rail spacers are required on confirmed fitment applications. A professional ECU tune using the provided Injector Dynamics characterization data (Dead Time and Flow vs. Pressure tables) is strongly recommended and required any time high-flow injectors are installed. Do not operate the vehicle with high-flow injectors without a calibrated tune.

Frequently Asked Questions

Is the ID1300x² compatible with E85?
Yes. The ID1300x² was specifically designed for alternative fuels including E85 and features all stainless steel internals for maximum resistance to the corrosive effects of ethanol. It is compatible with all known fuels.

Can I run these injectors on pump gasoline?
Yes. The ID1300x² retains a minimum fuel mass compatible with gasoline use, providing exceptional idle quality and smooth cruise behavior on pump gas when properly tuned.

Are these CARB compliant?
No. These injectors are not legal for sale or use in California on any pollution-controlled motor vehicle. They are intended for competition/racing use only. Consult your local regulations before purchase.

Do I need a tune after installing these injectors?
Yes. A professional ECU calibration using the Injector Dynamics Dead Time and Flow vs. Pressure characterization data is mandatory for safe and proper operation.
