Injector Dynamics Fuel Injectors — Universal Fitment

Not every build fits neatly into a vehicle-specific listing. Engine swaps, custom fuel rail setups, standalone ECU conversions, and one-off motorsport builds often require a specific combination of injector body length, O-ring size, and connector type that does not match any factory application. The Injector Dynamics Universal Fitment range gives you access to the full ID injector lineup — ID1050x, ID1300x, ID1750x, and ID2600x — in every available physical configuration, so you can select the exact specification your build requires.

How to Read ID Fitment Codes

Each Injector Dynamics universal fitment variant is described by a code that specifies the physical dimensions and connector type. Understanding the code ensures you select the correct injector for your fuel rail, intake manifold, and wiring harness.

The format is: Body Length . Top O-Ring . Lower O-Ring/Connector

Body Length — measured in millimetres. The three standard lengths are 34mm (short body, common on modern direct-fit applications), 48mm (mid-length, used on many Japanese four-cylinder applications including Subaru WRX, Nissan SR20, and Honda K-series), and 60mm (long body, the traditional standard for older Japanese and universal applications).

Top O-Ring — the O-ring that seals the injector into the fuel rail. Common sizes are 14mm (standard for most aftermarket fuel rails) and 11mm (used on some older Japanese applications and specific Bosch rails).

Lower O-Ring/Connector — the seal and connector at the intake manifold end. Common options include 14 (14mm standard O-ring), 15 (15mm O-ring for select European applications), 14B (14mm with extended nose for deeper manifold pockets), D (Denso-style connector for Toyota/Lexus applications), O (OBD2-style connector), WRX (Subaru-specific connector), F20 (Ford EcoBoost connector), and R35 (Nissan GT-R specific).

Common Universal Fitment Selections

48.14.14 — 48mm body, 14mm top, 14mm lower. One of the most common aftermarket configurations. Suits most Japanese four-cylinder applications with aftermarket fuel rails including Subaru EJ, Mitsubishi 4G63, and Honda B-series with aftermarket top-feed rails.

60.14.14 — 60mm body, 14mm top, 14mm lower. The traditional long-body universal fitment. Suits older Japanese applications, RB26 with aftermarket rails, and many custom fuel rail configurations.

34.14.14 — 34mm short body. Common on modern platforms including the EA888 Gen 3 (VW/Audi MQB) and newer compact intake manifold designs.

48.11.14 — 48mm body with 11mm top O-ring. Suits applications with Bosch-style fuel rails using the smaller 11mm rail bore.

48.14.R35 — 48mm body with Nissan GT-R R35 specific lower connector. Direct fit for the R35 fuel rail without adapter modification.

If you are unsure which fitment code matches your fuel rail and manifold, measure the fuel rail bore diameter (top O-ring), the manifold pocket depth (body length), and check the wiring connector type on your existing injectors or harness. If in doubt, contact us with your engine, fuel rail brand, and intake manifold details and we will confirm the correct specification.

Available Injector Sizes

All universal fitment codes are available in the full Injector Dynamics range — ID1050x (1065cc/min at 3 bar), ID1300x (1340cc/min), ID1750x (1728cc/min), and ID2600x (2225cc/min). Each size ships with complete characterisation data including dynamic slope flow rates, dead time values across voltage and pressure ranges, and dynamic flow matching. This data is compatible with all major ECU platforms including Haltech, MoTeC, Link, COBB, Hondata, HP Tuners, EFI Live, and AEM.

Pairing with the Right Fuel System

Universal fitment injectors are most commonly used in custom builds with aftermarket fuel rails. At Chicane Australia, we stock Radium Engineering fuel rails, plumbing kits, and fuel pump hangers for a wide range of engines — all featuring 17.5mm bore billet construction designed to support high-flow injectors. Whether you are building a return-style fuel system from scratch or upgrading an existing setup, we can help you spec the complete system from pump to rail to injector.

Contact us with your engine, power target, fuel type, and fuel rail details — we will confirm the correct injector fitment code and recommend the supporting hardware to match.
