Why Install This?
Benefits
- Moderate install — doable in a home garage with some mechanical experience
What Does This Do?
When you replace the factory MDS lifters with non-MDS lifters, the oil passages that fed the MDS solenoids are left open. These passages MUST be sealed or you'll lose oil pressure — the oil that should be lubricating your bearings and cam will be dumping out through open passages instead. These simple aluminum plugs press into the lifter valley to seal those passages. It's a $30 part that prevents thousands in engine damage. Four plugs are needed per engine (one for each MDS solenoid bank). Automatic transmission HEMIs only — manual trans models don't have MDS.
Fitment Notes
Fits 5.7L and 6.4L HEMI with MDS (automatic trans only).
