AISIN Engine Oil Pump P/N:OPT-103

$321.99

Description

Keep pressurized oil moving to every critical engine component with the AISIN Engine Oil Pump OPT103. It installs as a direct-fit replacement across a range of Lexus and Toyota V8s, including the 1998-2000 Lexus GS400 [V8-4.0L], 2001-2007 Lexus GS430 [V8-4.3L], 2005-2009 Lexus GX470 [V8-4.7L] and 2005-2009 Toyota 4RUNNER [V8-4.7L] — see the Buyer's Guide tab for the full list of applications and engines.

The oil pump draws oil from the sump and delivers it under pressure through the engine's oil galleries to lubricate the bearings, valvetrain and other moving parts. If a worn pump is behind low oil pressure, a lit oil-pressure warning light, or ticking from oil-starved components, this replaces it.

Aluminum die-cast construction: engineered for size and weight reduction without sacrificing performance.
Lubricates critical components: helps maintain oil supply to keep the engine's moving parts protected.
Controlled pressure: designed to deliver ideal oil pressure without creating excess load.
Country of origin: Japan.
