Firstly, Buy Mitsubishi OEM Cylinder Block Bushing Evo X 1050A003. The Mitsubishi OEM Cylinder Block Bushing M14x19 for Evo X (1050A003) is a genuine Mitsubishi factory replacement component designed for the cylinder block assembly of the Mitsubishi Lancer Evolution X. This OEM dowel bushing is used in the 4B11 engine block and provides the correct factory-specification locating component for an Evo X engine rebuild, restoration, or replacement block assembly.

The 1050A003 is specified as an M14x19 cylinder block dowel bushing and is listed for the Mitsubishi Lancer Evolution X chassis CZ4A. STM Tuned confirms that two of these bushings are used in the Evo X block and that the part is sold individually.

Mitsubishi OEM Cylinder Block Bushing M14x19 – 1050A003

When rebuilding a Mitsubishi Evolution X 4B11 engine, every locating component matters. Large engine components receive most of the attention, but small bushings and dowel components help ensure that the engine is assembled using the correct factory hardware.

The Mitsubishi OEM Cylinder Block Bushing M14x19 is manufactured for its specified Mitsubishi application and identified by OEM part number 1050A003. It is a practical replacement when an original bushing is missing, damaged, or being replaced during a complete engine rebuild.

For Evo X owners building a replacement short block, refreshing an original engine, or restoring a vehicle to OEM specification, using the correct Mitsubishi part number helps avoid substituting an incorrect generic component.

Key Features

• Genuine Mitsubishi OEM replacement component
• Mitsubishi part number 1050A003
• M14x19 cylinder block dowel bushing
• Designed for the Mitsubishi Lancer Evolution X
• Fits the CZ4A chassis
• Used with the 4B11 engine block
• Two bushings are used in the Evo X block
• Sold individually

STM Tuned identifies 1050A003 as the genuine OEM Mitsubishi cylinder block dowel bushing for all Evo X models and states that two are used in the diagram.

Firstly: Genuine Mitsubishi OEM Construction

The main benefit of the 1050A003 is that it is a genuine Mitsubishi OEM component. For a high-performance engine such as the Evo X 4B11, using the correct factory hardware is especially useful during a detailed engine rebuild.

OEM engine components are identified by their original Mitsubishi part numbers, making them easier to cross-reference with factory diagrams and parts catalogs. This is valuable when assembling a bare cylinder block or replacing small components that may have been lost during disassembly.

Instead of relying on a generic bushing with uncertain dimensions, the 1050A003 gives the engine builder a specific Mitsubishi part-number reference for the intended cylinder-block application.

Secondly: Correct M14x19 Cylinder Block Bushing

The 1050A003 is identified as an M14x19 bushing, making accurate part identification important when ordering replacement engine hardware.

A cylinder block contains several different pins, bushings, plugs, and related components. They can look similar at first glance, but their dimensions and intended locations are not necessarily interchangeable.

The Mitsubishi parts catalog identifies 1050A003 specifically as a BUSHING, CYLINDER BLOCK, with diagram reference 01396.

This makes the OEM part number the best reference when ordering the component for an Evo X engine rebuild.

Thirdly: Ideal for Evo X 4B11 Engine Rebuilds

The Mitsubishi Lancer Evolution X uses the turbocharged 4B11 engine, and a complete engine rebuild often involves removing the cylinder block and its smaller factory components.

During disassembly, bushings can be misplaced, damaged, or intentionally removed for inspection. When rebuilding the block, replacing questionable or missing hardware with genuine Mitsubishi components helps keep the assembly consistent with the original configuration.

The 1050A003 is therefore useful for:

• Evo X engine rebuilds
• Bare cylinder block assembly
• 4B11 engine restoration
• OEM-specification engine builds
• Replacement engine blocks
• Engine machining and reassembly
• Missing or damaged bushing replacement

Applications

The Mitsubishi OEM Cylinder Block Bushing 1050A003 is listed for the Mitsubishi Lancer Evolution X, chassis CZ4A, covering the 2008–2015 Evolution X application. STM Tuned specifically lists the vehicle fitment as CZ4A 2008–2015 Evolution X.

The part is also identified in Mitsubishi parts-catalog data as a cylinder block bushing within the engine cylinder-block assembly.

Because Mitsubishi part numbers can appear in multiple catalog applications, checking the VIN and applicable factory parts diagram is recommended if there is any uncertainty about fitment.

Why Replace the Cylinder Block Bushing?

Small engine components can be easy to overlook during an engine rebuild. However, the correct locating hardware is part of the overall factory assembly and should be accounted for when rebuilding a cylinder block.

Replacing a missing or damaged 1050A003 also helps avoid mixing different components from unrelated applications. This is particularly important when assembling an engine from a bare block and separately sourced internal parts.

For an OEM restoration, the correct Mitsubishi part number also makes the parts inventory easier to document and verify.
