Your cart is empty. NEW 5.7 HEMI NON-MDS Engine Expansion Plug
Note: This plug is used in place of the MDS Valve on engines that don't have a Multiple Displacement System (MDS). Most 5.7L engines from 2003-08 had MDS that shut down some cylinders to conserve fuel. Four of these plugs are used with two sets of Tappets 312-53021720AE to convert a 5.7L engine to non-MDS. Ideal for engine conversions in street rods & muscle cars that don't use MDS.

Genuinely don't waste your money on the MOPAR versions they're the exact same. These bad boys have one job, fill a hole, and they do just that!

Bought these for my 08 ram. Soon after got T-boned by a lady making a illegal you turn because she left her phone at her workplace. Never got to install but appeared to be of good quality.

Cheaper than oem, but a super tight fit. Which I guess is good. But they take some force to get in.
