Aem K-series Headers Installation: Step-by-step Guide for Maximum Gains

The AEM K-Series headers are a popular upgrade for enthusiasts looking to enhance the performance of their K-Series engines. This step-by-step guide will walk you through the installation process to ensure maximum gains and efficiency from your new headers.

Tools and Materials Needed

  • Socket set
  • Wrench set
  • Torque wrench
  • Jack and jack stands
  • Header gaskets
  • High-temperature exhaust sealant
  • Safety goggles
  • Gloves

Preparation Steps

Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Gather all tools and materials to streamline the process.

1. Raise the Vehicle

Using a jack, lift the front of the vehicle and secure it with jack stands. This will provide better access to the exhaust system.

2. Disconnect the Battery

For safety, disconnect the negative terminal of the battery to prevent any electrical issues during installation.

Removing the Old Headers

Begin by removing the old headers to make way for the new AEM K-Series headers. Follow these steps carefully.

1. Remove Exhaust Components

Loosen and remove any bolts securing the exhaust components connected to the old headers. This may include the catalytic converter and exhaust pipes.

2. Unbolt the Old Headers

Locate the bolts securing the old headers to the engine block. Use the appropriate socket and wrench to remove these bolts. Carefully pull the headers away from the engine.

Installing the AEM K-Series Headers

With the old headers removed, it’s time to install the new AEM K-Series headers. Follow these steps for a successful installation.

1. Prepare the New Headers

Before installation, inspect the new headers for any damage. Apply high-temperature exhaust sealant to the header gaskets to ensure a proper seal.

2. Position the New Headers

Carefully position the new AEM headers onto the engine block, aligning them with the bolt holes. It may be helpful to have a second person assist with this step.

3. Bolt the Headers in Place

Using the original bolts, secure the headers to the engine block. Start by hand-tightening the bolts to ensure proper alignment, then use a torque wrench to tighten them to the manufacturer’s specifications.

Reconnecting Exhaust Components

Once the headers are securely in place, it’s time to reconnect the exhaust components that were removed earlier.

1. Reattach the Catalytic Converter and Exhaust Pipes

Align and bolt the catalytic converter and exhaust pipes back to the new headers. Ensure all connections are tight and secure.

2. Double-Check All Bolts

Before lowering the vehicle, double-check all bolts and connections to ensure everything is properly secured. This step is crucial to avoid leaks or issues later on.

Final Steps

With the installation complete, it’s time to finish up and ensure everything is in order.

1. Reconnect the Battery

Reconnect the negative terminal of the battery. This will restore power to the vehicle’s electrical system.

2. Lower the Vehicle

Carefully lower the vehicle off the jack stands and back onto the ground.

3. Start the Engine

Start the engine and allow it to idle for a few minutes. Listen for any unusual sounds that may indicate a leak or installation issue.

Conclusion

Installing AEM K-Series headers can significantly improve engine performance and efficiency. By following this step-by-step guide, you can ensure a successful installation that maximizes your vehicle’s gains.
