• 2006-2011 Mitsubishi Eclipse (4G69, 2.4L SOHC MIVEC I4, FWD)

Fitment Notes

• This is the ACL Orbit OEM-equivalent (standard output) oil pump - flow and pressure characteristics meet or exceed OEM specifications; it is not a high-volume performance pump and is not recommended for high-power built engines
• Fits all Lancer Evolution IV through IX trim levels including RS, GSR, SE, MR, GT, and Tommi Makinen Edition (TME) variants
• Fits the Lancer Evolution IX Wagon (CT9W) equipped with the 4G63T MIVEC engine
• Does NOT fit the Lancer Evolution X (EVO 10) - the X uses the 4B11T engine and requires a different oil pump
• Does NOT fit the Lancer Evolution I, II, or III - earlier-generation 4G63T oil pump architecture differs
• Compatible with all global market EVO IV-IX variants (JDM, USDM, EUDM)
• Plug-and-play installation - no modifications required; direct OEM replacement

Features

• OEM-equivalent flow and pressure output - meets or exceeds factory Mitsubishi oil pump specifications for 4G63T, 4G64, and 4G69 engines
• Precision steel-copper alloy (FC0205) gerotor set for dependable, long-service lubrication under sustained engine operation
• Tight housing-to-gerotor tolerances engineered to maintain optimum oil pressure and flow across the engine's full RPM range
• Die-cast ADC-12 aluminum pump housing anodized for corrosion resistance and long service life
• Pre-loaded at the factory to prevent dry-start oil starvation at initial engine start-up after installation
• Individually inspected and flow-tested prior to shipping to verify pressure and volume specifications
• TS16949 and ISO certified manufacturing process for consistent quality control
• Direct bolt-on fitment - no modification or custom fabrication required
• Complete gasket set included for a clean, leak-free installation
• Backed by a 12-month / 12,000-mile limited warranty

Product Description

The ACL Orbit OPMB1176 is an OEM-equivalent front cover oil pump engineered as a direct replacement for the Mitsubishi 4G63T, 4G64, and 4G69 engines. It covers the full Lancer Evolution IV through IX lineup (1996-2007) across all trim levels - including RS, GSR, SE, MR, and the Tommi Makinen Edition - as well as the Eclipse, Galant, and Outlander models equipped with the 4G64 and the 2006-2011 Eclipse with the 4G69. Oil pump replacement is a critical service item in any engine rebuild or high-mileage refresh, as a worn or failing pump directly compromises lubrication pressure to the crankshaft, camshafts, and turbocharger on the 4G63T - a failure mode that can lead to rapid and catastrophic engine damage.

The OPMB1176 uses a precision steel-copper alloy (FC0205) gerotor set housed within a die-cast ADC-12 anodized aluminum body. The gerotor tolerances are machined to tight specifications to maintain consistent oil pressure and flow from cold start through high-RPM operation, matching or exceeding the factory Mitsubishi pump's output characteristics. The housing is pre-loaded at the factory to avoid dry-start conditions, eliminating the risk of the pump running unlubricated during the critical first seconds after an engine rebuild. Each unit is individually inspected and flow-tested before it leaves the factory, and the manufacturing process is TS16949 and ISO certified - the same standards applied to original equipment supplier production.

It is important to note that the OPMB1176 is ACL's OEM-equivalent standard output pump, designed for factory-spec rebuilds and naturally aspirated or mildly modified engines. It is not a high-volume performance pump and is not recommended for high-power forced induction builds where elevated oil pressure demand exceeds OEM requirements - for those applications, ACL's dedicated race-spec oil pump should be selected instead. Installation is plug-and-play with no modifications required, and a complete gasket set is included. The pump is covered by ACL's 12-month / 12,000-mile limited warranty against defects in materials and workmanship.
