Injector Dynamics Fuel Injectors — Universal Fitment

Engine swaps, custom fuel rail setups, standalone ECU conversions and one-off motorsport builds often need a combination of injector body length, O-ring size and connector type that does not match any factory application. This universal fitment range covers the full Injector Dynamics XDS injector lineup — ID1050x, ID1300x, ID1750x and ID2600x — in every available physical configuration, alongside ID fuel system hardware such as the F1250 and IDF750 in-line fuel filters, replacement elements, O-ring kits and the BPC100 brushless pump controller. Browse the full Injector Dynamics range for vehicle-specific listings.

How to read ID fitment codes

Each universal fitment variant is described by a code that specifies the physical dimensions and connector type. 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 — 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. 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 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 (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.

Available injector sizes

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

Installation & What You'll Need

Before ordering, 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. Note that plug-and-play harness adapters may be required where the ID connector differs from your loom.

Larger injectors need a supporting fuel system. This collection also includes ID filtration and control hardware — the F1250 in-line fuel filter (available as a kit with bracket, filter only, mount only, or replacement element), the IDF750 fuel filter in black with replacement elements and O-ring kits, a dual fuel pressure/temperature sensor to suit the ID750 filter, and the BPC100 brushless pump controller with or without the E5LM fuel pump.

Injectors must be recalibrated in the ECU using the supplied characterisation data before the engine is run. Installation and tuning by a qualified professional automotive technician is strongly recommended.

FAQ

What does a fitment code like 48.14.14 mean?

It lists body length, top O-ring size and lower O-ring or connector type in millimetres — in this case a 48mm body with a 14mm top O-ring and a 14mm lower O-ring.

Which injector size should I choose?

Size is chosen from your power target, fuel type and number of cylinders. The range covers ID1050x, ID1300x, ID1750x and ID2600x, with flow rates listed above.

Do these injectors come with characterisation data?

Yes. Every Injector Dynamics injector ships with dynamic slope, offset and dead time data for use with major ECU platforms including Haltech, MoTeC, Link, COBB, Hondata, HP Tuners, EFI Live and AEM.

Can I use universal injectors with a factory fuel rail?

Only if the body length, O-ring sizes and connector match your rail and manifold. If they do not, a vehicle-specific ID listing or an aftermarket rail may be required.
