Mitsubishi OEM Wastegate Actuators for Evo 8/9

Firstly, Buy the OEM Evo wastegate actuator online for your Mitsubishi Evo 8 or 9. Restore proper turbo boost control with OEM Evo wastegate actuator replacements for the Mitsubishi Lancer Evolution VIII and IX. These genuine Mitsubishi actuators are designed for their respective factory turbocharger applications. They offer a direct replacement option when the original actuator is worn, damaged, or no longer operating correctly.

The wastegate actuator plays an important role in turbocharger operation. It controls the internal wastegate, helping regulate exhaust flow through the turbine. When the actuator works correctly, it helps the turbo system manage boost as intended.

Mitsubishi uses different actuators for the Evo VIII and Evo IX. The Evo VIII uses part number MN153089, while the Evo IX uses part number 1515A056. Selecting the correct version is essential because the mounting arrangement and actuator rod differ between the two applications.

If you are maintaining a factory-turbo Mitsubishi Evo or restoring the original boost-control setup, these OEM replacements offer a vehicle-specific solution. Check your model year and turbocharger before ordering.

OEM Evo Wastegate Actuator Features

These genuine Mitsubishi wastegate actuators are intended for factory-style replacement applications on the Evo VIII and Evo IX.

Key product details include:

• Brand: Mitsubishi
• Product type: OEM internal wastegate actuator
• Vehicle application: Mitsubishi Lancer Evolution VIII and IX
• Evo VIII part number: MN153089
• Evo IX part number: 1515A056
• Evo VIII fitment: 2003–2005
• Evo IX fitment: 2006
• Package contents: One actuator, selected for the required application

Always match the part number to your vehicle and turbocharger. Model year alone may not be enough if the turbo has been replaced or modified.

Choose the Correct Evo 8 or Evo 9 Actuator

Although the Evo VIII and IX share the 4G63 engine family, their factory turbocharger configurations differ. Their wastegate actuators are not interchangeable as standard replacements.

Mitsubishi Evo 8 Wastegate Actuator — MN153089

The MN153089 actuator is listed for the 2003–2005 Mitsubishi Lancer Evolution VIII. Choose this version when replacing the actuator on a compatible factory Evo VIII turbo.

Before buying, check the turbocharger and confirm that the existing actuator matches this part number. If your car has an Evo IX turbo conversion or an aftermarket turbo, additional fitment checks are necessary.

Mitsubishi Evo 9 Wastegate Actuator — 1515A056

The 1515A056 actuator is listed for the 2006 Mitsubishi Lancer Evolution IX. It is the appropriate OEM option for the compatible factory Evo IX turbocharger.

Buy the OEM Evo wastegate actuator online for your Mitsubishi Evo 8 or 9, Select the correct factory part number and confirm turbo fitment before ordering.

The Evo IX actuator uses a different mounting and rod arrangement from the Evo VIII version. Installing the wrong actuator can interfere with wastegate movement and boost control.

Important: Do not choose between these parts based only on appearance or engine type. Confirm the correct actuator for your actual turbocharger.

What Does a Turbo Wastegate Actuator Do?

A wastegate actuator helps control how much exhaust gas flows through the turbocharger turbine. It operates the wastegate flap, allowing exhaust gas to bypass the turbine when required.

This process helps regulate turbo speed and boost pressure. The actuator’s spring and pressure response influence when the wastegate begins to open.

If the actuator develops a fault, the vehicle may experience inconsistent boost, underboost, or other turbo-control problems. However, similar symptoms can also result from boost leaks, faulty solenoids, damaged hoses, or problems with the wastegate itself.

Replacing the actuator may resolve the issue when the actuator is confirmed to be the cause. A proper diagnosis helps prevent unnecessary parts replacement.

Benefits of Genuine Mitsubishi OEM Replacement Parts

Choosing an OEM actuator helps maintain the original component specification for the intended turbo application.

Firstly, the correct factory part provides the intended mounting arrangement for its matching turbocharger.

Secondly, the original actuator specification helps preserve the factory boost-control setup when the rest of the system is operating correctly.

Thirdly, using the correct Mitsubishi part number makes it easier to verify compatibility before installation.

An OEM replacement does not automatically increase horsepower or raise the vehicle’s safe boost limit. Its main purpose is to replace the original component with the correct application-specific part.

Installation and Fitment Checks

Before installing a replacement actuator, inspect the turbocharger and surrounding components. Confirm that the wastegate arm moves correctly and that the mounting points are in good condition.

Check the actuator rod adjustment and preload against the manufacturer’s service procedure. Incorrect adjustment can affect wastegate operation and boost pressure.

After installation, verify that the actuator moves smoothly and that the boost-control system operates correctly. If boost levels remain inconsistent, inspect the hoses, boost-control solenoid, and wastegate mechanism.

If you are unsure about the installation or adjustment, use a qualified Mitsubishi specialist or turbocharger technician. Correct setup is important for reliable engine operation.

Frequently Asked Questions

Does this product fit both the Evo 8 and Evo 9?

The product range covers both models, but each requires its own actuator. The Evo VIII uses MN153089, while the Evo IX uses 1515A056.

What is the part number for the Evo 8 actuator?

The listed OEM part number is MN153089 for the 2003–2005 Mitsubishi Lancer Evolution VIII.

What is the part number for the Evo 9 actuator?

The listed OEM part number is 1515A056 for the 2006 Mitsubishi Lancer Evolution IX.

Can I install an Evo 9 actuator on an Evo 8 turbo?

They are not standard interchangeable replacements. The mounting arrangement and rod geometry differ, so use the actuator specified for your turbocharger.

Will replacing the actuator increase horsepower?

Not by itself. An OEM actuator is intended to restore correct wastegate operation. Any performance change depends on the condition of the original part and the rest of the turbo system.

How do I know if my wastegate actuator needs replacement?

Possible signs include inconsistent boost or underboost, but these symptoms can have several causes. Check for leaks and other boost-control faults before replacing the actuator.

Is the actuator sold with the turbocharger?

No. The listed product is one wastegate actuator. The turbocharger is not included. Shop Mitsubishi OEM wastegate actuators at Evomotorparts.com and select the correct Evo VIII or Evo IX part number for your turbocharger before ordering.
