ID1300-XDS, for 02-09 RSX / K-series. 14mm (grey) adapter top. Set of 4.

The ID1300 is an all new injector, designed in partnership with Bosch Motorsport. This collaboration has given us the ability to design a high flow injector with characteristics specific to the needs of the motorsport tuner. The ID1300 was designed with alternative fuels in mind, and is the only performance injector available with all stainless internals. It is compatible with all known fuels, and will stand up to the corrosive nature of alcohol better than any injector on the market.

While the ID1300 was designed with an eye towards ethanol fueled engines, we have accounted for the occasional need to convert back to gasoline. The ID1300 has a minimum fuel mass compatible with gasoline use, and will provide exceptional idle and cruise behavior under these conditions. In addition to its multi-fuel capabilities, the compact body of the ID1300 allows fitment in 200+ applications, making it the most versatile injector in our lineup. The 1300 has continued to be refined and improved over the years, and the 1300-XDS is the latest and best version to date.

Frequently Asked Questions About the ID1300-XDS Injectors

RSX 02-09 | ID1300-XDS | Injector Dynamics | 1300.48.14.14.4

The ID1300-XDS (1335 cc/min at 43.5 psi) is sized for high-boost Honda K-Series engines. This set of 4 provides flow capacity for forced induction E85 setups well into the 600 to 750+ wheel horsepower range, offering ample margin for large turbocharger builds.

Is the 48mm short body length (PN: 1300.48.14.14.4) a direct drop-in replacement for the RSX factory fuel rail?

Yes, it is a direct fit. This ID1300-XDS set is configured to the specific short-body 48mm O-ring to O-ring length required for the RSX K-Series engine. It installs directly into the factory fuel rail and manifold bosses without requiring spacers.

Does this USCAR ID1300-XDS set require PNP adapters to connect to the Acura RSX factory harness?

Yes, adapters are required. The ID1300-XDS uses the modern USCAR connector. The factory RSX harness uses a Denso style connector. You will need four USCAR to Denso PNP adapters (ID P/N 90.3) for a clean, non-splicing electrical hookup.

Where can my tuner find the complete Injector Dynamics Dead Time data for the ID1300-XDS for tuning the RSX K-Pro or FlashPro?

Injector Dynamics provides validated Dead Time (Latency) and Flow vs. Pressure tables (based on ID1300x2). This data is mandatory for tuning platforms like Hondata K-Pro to ensure accurate fuel metering during both low-pulse idle and the high-demand VTEC crossover event.

Does the ID1300-XDS maintain a smooth idle on gasoline, or is it too large for a daily-driven K20 engine?

The ID1300-XDS is specifically engineered for excellent drivability on gasoline. Its superior Dual Slope Matching technology guarantees highly linear flow at very low pulse widths, ensuring a stable, near-OEM idle quality despite the high flow rate.
