Subaru STI 07-21 Injector Dynamics 1340cc Injectors-48mm Length - 11mm Gold Top/Denso And -204 Low Cushion (Set of 4) - 1300.48.11.WRX.4

Injector Dynamics ID1300-XDS Fuel Injectors — Subaru WRX/STI (Set of 4)

The four-cylinder ID1300 in Subaru top-feed fitment — 48mm body, 11mm gold adapter tops, WRX-16B bottom adapters. Covers 02-14 WRX, 07-21 STI, 07-12 Legacy GT, and 06-13 Forester XT.

Designed in partnership with Bosch Motorsport, the ID1300 is built specifically for motorsport rather than adapted from a production part. It's the only performance injector available with all stainless internals, compatible with all known fuels and built to stand up to the corrosive nature of alcohol better than anything else on the market.

The reason it's stayed the standard: it delivers high flow without giving up idle and cruise quality. The ID1300 has a minimum fuel mass compatible with gasoline use, so a car set up for E85 still behaves properly on pump gas. Excellent low pulsewidth extension keeps cylinder-to-cylinder consistency at idle even on an engine fueled for four-figure power.

The compact body fits over 200 applications, making it the most versatile injector in the ID lineup.

Nominal flow 1340 cc/min at 3.0 bar (43.5 psi), maximum differential fuel pressure 6.0 bar (87 psi). USCAR connector.

Sized for 120-160 hp per injector — roughly 640 hp and up on a set of four.

Not plug-and-play — includes clips and pins that require crimping. Either re-pin the factory harness or add the optional plug-and-play adapters.
