Oil Pump for Infiniti G35 (2003-2007) 3.5L

Direct-Replacement Oil Pump Kit for 2003-2007 Infiniti G35 (V35)

What it Does: The replacement oil pump circulates pressurized motor oil through the 2003-2007 Infiniti G35 engine to prevent catastrophic bearing wear and maintain critical hydrodynamic lubrication across the valvetrain.

The Stock Infiniti G35 Low Oil Pressure Vulnerability

Factory oil pumps on the VQ35DE are prone to internal gear wear, relief valve sticking, and housing micro-scoring after years of heat cycles and high-RPM operation. Over time, enlarged gerotor gear clearances bleed off critical oil volume at idle and under high load. This pressure drop starves the camshaft journals, rod bearings, and timing chain tensioners, leading to top-end tick, guide wear, and premature bearing spun failures on high-mileage V35 chassis.

The Engineering Solution

This replacement oil pump assembly is manufactured to tight tolerances to restore factory-spec oil volume and oil gallery line pressure. Featuring high-strength cast alloy construction and precision-machined internal gears, it mitigates cavitation and oil pressure drop-off across the entire RPM band. The assembly includes a direct-fit replacement gasket and crankshaft O-ring to replace degraded factory seals, restoring an airtight oil passage and preventing front main leaks behind the timing cover.

Frequently Asked Questions & Fitment Warnings

Does this fit the V35 G35?

Yes, this is a direct fit for the 2003-2007 Infiniti G35 equipped with the VQ35DE engine. This kit does not fit 2007+ G35 Sedan models equipped with the dual-intake VQ35HR engine.

Do I need to prime the oil pump prior to first startup?

Yes, you must prime the pump with clean engine oil or assembly lubricant prior to installation to ensure immediate fluid suction and prevent dry startup friction.

The Infiniti Performance Standard

Protect your high-revving VQ engine from internal oil starvation and sustain stable hydrodynamic oil film strength during hard acceleration and spirited driving.
