These are the same injectors found in new M54B30 applications, from the same manufacturer as Genuine BMW.
OEM Part #: 13537546245
We’ve had issues using rebuilt injectors, as they are very fragile and can leak after install. So we only use new injectors as replacements. All of our engine builds get new Continental (previously labeled as Siemens VDO) injectors, as do our SpecE46 builds.
Use a light coat of petroleum jelly on the o-rings prior to install and handle with care.
