FAQ

It is intended for late-1999 (1999.5)–2003 AD-code engines. Earlier AB/AE applications should use the correct code-matched injector.

Yes—at 230cc these hybrids need custom tuning and sufficient airflow. An upgraded turbo and strong HPOP help maintain ICP and EGT control.

Use new external o-rings and nozzle washers on each injector. We recommend the MAHLE GS33440 or DTECH DT730027 kits listed above.
