OEM Mitsubishi Oil Jet Check Valve MD372046 for Evo 7/8/9/X

Firstly, BUY OEM Mitsubishi Oil Jet Check Valve MD372046 for Evo 7/8/9/X, The OEM Mitsubishi Oil Jet Check Valve MD372046 is a genuine Mitsubishi engine component designed for the piston oil-jet system used in Mitsubishi Lancer Evolution applications. This valve is applicable to the Mitsubishi Evolution 7, Evolution 8, Evolution 9, and Evolution X, making it an important replacement component for engine rebuilds, maintenance, and performance-focused builds.

Firstly, the oil jet check valve plays an important role in controlling oil flow to the engine’s piston oil jets. The oil jet system delivers engine oil toward the underside of the pistons, helping with piston cooling and lubrication during demanding engine operation. Secondly, maintaining the correct oil-jet components is particularly important when rebuilding a turbocharged Mitsubishi engine such as the 4G63T or 4B11T.

This OEM Mitsubishi Oil Jet Check Valve is sold individually, so a complete replacement set requires four valves. Always verify the OEM part number and engine application before ordering.

Why Replace the Oil Jet Check Valve?

The piston oil-jet system is an important part of thermal management in a high-performance turbocharged engine. During high-load and high-boost operation, pistons experience substantial heat. Engine oil directed underneath the pistons helps remove heat and provides additional lubrication.

A damaged, restricted, or contaminated check valve can interfere with the intended operation of the oil-jet system. For this reason, the oil jet check valves should be carefully inspected whenever an Evo engine is disassembled.
