Oil Pump for Infiniti M35 (2006-2008) 3.5L

High-Flow Replacement Oil Pump Assembly for 2006-2008 Infiniti M35 (Y50)

What it Does: The Oil Pump Assembly replaces the worn factory oil pump on the 2006-2008 M35 to restore critical hydrodynamic lubrication pressure and prevent catastrophic bearing starvation across the engine block.

The Stock Infiniti M35 Oil Pressure Vulnerability

High-mileage VQ35DE engines in the Y50 chassis frequently suffer from pressure relief valve fatigue, inner/outer gear rotor wear, and thermal degradation of the factory front main seal. As pump housing tolerances loosen over thousands of heat cycles, the engine experiences substantial oil pressure drop at hot idle and elevated RPMs. This loss of line pressure directly compromises rod and main bearings while causing hydraulic timing chain tensioner slack, leading to VTC timing errors and irreversible internal mechanical wear.

The Engineering Solution

Machined to tight OE tolerances, this direct-replacement oil pump restores precise lubrication volume across the entire VQ35DE oil gallery circuit. Featuring high-strength cast alloy construction and precision-meshed gerotor gears, the assembly resists cavitation, eliminates fluid blow-by, and maintains consistent oil pressure under hard load. The included pre-formed gasket and fluoroelastomer O-ring ensure a leak-free seal against the front engine cover, resisting high operating oil temperatures and oil degradation.

Frequently Asked Questions & Fitment Warnings

Does this fit the Y50 M35?

Yes, this is a direct fit for the 2006-2008 Infiniti M35 equipped with the VQ35DE engine. Does not fit M45 models equipped with the 4.5L VK45DE V8 engine or 2009+ models equipped with the VQ35HR engine.

Do I need to prime the pump prior to installation?

Yes, always pre-lube and prime the pump rotors with clean motor oil prior to installation and verify oil pressure with a mechanical gauge before initial start-up.
