FUEL INJECTOR COMPATIBILITY
OEM Injectors-The Radium Engineering fuel rail features 11mm injector bores making it compatible with the factory Subaru EZ30 Phase-I "air-assist" fuel injectors. No modifications are needed. If preparing to use aftermarket fuel injectors.

Aftermarket Injectors-The Phase-I EZ30 uses air-assist emissions equipment. These engines use a unique OEM fuel injector that is not replicated in the aftermarket. In order to use universal aftermarket fuel injectors, these cylinder heads require the provided Radium injector seats. When these injector seats are installed into the air-assist cylinder heads, an aftermarket injector that is 48mm long with 11mm upper O-ring and 14mm lower O-ring must be used. The following universal injectors have been verified to be compatible. However there are others on the market that will work that are not listed here.
