These high-quality Hana injectors are low-noise, fast-opening and provide accurate fuelling. They have an impedance of 1.9 ohms. Check that your LPG ECU is capable of handling this impedance, before deciding to buy. The King ECU has the injector option “Matrix HD”, which matches these injectors. Hana injectors are sold individually. Be sure to select the correct number of injectors. This injector is designed to allow jets to be fitted to match the power output of the engine. Without a jet, it will power 41-50 bhp/cylinder. For 15-40 bhp/cylinder, you will need a jet of the correct size (sold separately). These injectors are designed to fit in a rail (sold separately).
