WRX 02-14 & STi 07-20 | ID1300-XDS | Injector Dynamics | 1300.48.11.WRX.4
ID1300-XDS, for WRX 02-14 & STi 07-20/ Turbo 2.0L & 2.5L. WRX-16B bottom adapters. 11mm (red) adapters
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 WRX & STi ID1300-XDS Injectors
What maximum E85 horsepower will the ID1300-XDS set support on a big-turbo WRX/STi (EJ20/EJ25 engine)?
The ID1300-XDS (1335 cc/min at 43.5 psi) is sized for high-boost Subaru applications. This set of 4 supports forced induction E85 setups well into the 600 to 750+ wheel horsepower range, offering ample fuel margin for aggressive turbo upgrades and highly boosted EJ-series engines.
Is the 48mm length of the 1300.48.11.WRX.4 injector a direct drop-in replacement for the 02-14 WRX and 07-20 STi 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 these model years. It includes an 11mm adapter top and specific bottom adapters (WRX-16B) for proper sealing and seating in the manifold/TGV housing.
Does this USCAR ID1300-XDS set require PNP adapters to connect to the Subaru factory harness?
Yes, adapters are required. The ID1300-XDS uses the modern USCAR connector. The factory WRX/STi 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 specific Dead Time data for the ID1300-XDS for tuning with Cobb Accessport or EcuTek?
Injector Dynamics provides validated characterization data (Dead Time and Flow vs. Pressure tables) specifically for the Subaru tuning platforms. This data is mandatory for the ECU to precisely control the injector during the fuel-heavy cold start enrichment phase, which is crucial for preventing misfires.
If my WRX/STi has a TGV (Tumble Generator Valve) delete, will this affect the injector fitment?
No, this injector set is compatible with TGV-deleted manifolds, but fitment should always be checked. More critically, the TGV delete removes emissions hardware and requires a custom tune to ensure proper idle air control.
