IMPORTANT NOTE

This is an aftermarket performance valve cover manufactured by Velocity Race Innovations and is not an OEM Mitsubishi product.

 

The Mitsubishi EVO 1/2/3 4G63 Billet Valve Cover is designed for applicable Mitsubishi EVO 1, EVO 2 and EVO 3 4G63 applications.Please verify your engine configuration and existing valve-cover setup before purchasing.

 

Because many 4G63 engines are modified, swapped or built using aftermarket components, fitment may vary depending on the specific engine configuration. Aftermarket camshafts, rocker/valvetrain components, cylinder-head modifications and other engine components may affect available clearance.

 

If you are unsure whether this Mitsubishi 4G63 Valve Cover is suitable for your engine, please contact us with clear photos of your current engine and valve-cover setup before ordering.

 

 

INSTALLATION

Professional installation is recommended.

 

Before installing the Mitsubishi EVO 1/2/3 4G63 Billet Valve Cover, inspect the cylinder-head sealing surface and ensure it is clean and free from oil, dirt and debris. Use the correct gasket and installation procedure specified for your particular engine configuration. The sealing surface should be inspected carefully before installation to ensure proper gasket contact and reliable sealing.

 

Additional clearance checks may be required depending on the camshaft, rocker/valvetrain configuration, ignition setup and other aftermarket components installed on the engine. The valve cover should be positioned carefully and the mounting bolts tightened evenly using the appropriate installation procedure. Avoid excessive tightening, as over-tightening may damage the gasket, sealing surface or mounting points and may result in oil leakage.

 

For competition and heavily modified 4G63 turbo engines, verify the breather, catch-can and crankcase ventilation routing before final installation. The included AN-10 breather fittings should be connected to a suitable crankcase ventilation system according to the requirements of the individual engine build.

 

 

WHY UPGRADE?

The Mitsubishi EVO 1/2/3 4G63 Billet Valve Cover is designed for customers looking for a rigid, durable and motorsport-oriented valve cover for a modified 4G63 engine.

 

The CNC billet construction provides a robust one-piece component, while the precision-machined sealing surface helps provide consistent gasket contact when installed correctly. Compared with a conventional cast valve cover, the billet construction gives the component a more substantial and refined appearance while providing a rigid platform for performance applications.

 

The increased internal volume is designed to provide additional space for managing engine blow-by, which can be particularly relevant to turbocharged and competition-oriented 4G63 builds. The included coil-on-plug adapter also allows the valve cover to be integrated into a suitable ignition configuration, depending on the specific engine setup.

 

The Competition Series 4G63 Performance Valve Cover is suitable for:

• Drag racing builds

PERFORMANCE NOTES

The Mitsubishi EVO 1/2/3 4G63 Billet Valve Cover is primarily a hardware, durability and engine-supporting upgrade.

 

The valve cover itself is not a direct horsepower-producing modification. Installing a billet valve cover alone does not automatically increase engine power.

 

Its primary benefits are the billet aluminium construction, rigid one-piece design, precision-machined sealing surface, increased internal volume and compatibility with performance-oriented ignition and crankcase ventilation configurations. For turbocharged 4G63 engines operating at elevated RPM and boost levels, correct crankcase ventilation and breather routing should be considered as part of the complete engine setup.

 

The valve cover can be combined with other supporting performance upgrades such as:

• Performance intake manifolds
• Fuel rails
• Upgraded ignition systems
• Engine management
• Crankcase ventilation systems
• Catch-can systems
• Other 4G63 performance hardware
