The LF-30 pump is a highly recommended upgrade to tracked or raced BMW E46 non-M’s. The LF-20 model is known to fail, with either the pump vanes breaking or the center shaft becoming loose and working its way out. Either failure will result in loss of power steering, or worse; trashing your rack with debris.
This kit includes a new OE pump and high pressure line. The install is plug and play.
We recommend Red Line D4 ATF fluid for these pumps. Do not use power steering fluid.
NOTE: If you haven’t removed your M14 power steering check valve, we highly recommend you do so. Failure to remove this check valve on track and race E46s can lead to pump and rack failure. You can purchase a non-check valve banjo bolt here.
The easiest way to tell if you have an LF-20 pump is to look at the mounting bracket. The LF-20 has a cast aluminum bracket, while the LF-30 has a stamped steel bracket.
