Installing AEM headers on your Miata can significantly enhance performance and sound. This guide will walk you through the process step-by-step, ensuring a smooth installation experience for beginners.
Tools and Materials Needed
- AEM headers
- Socket set
- Wrench set
- Torque wrench
- Gasket scraper
- New exhaust gaskets
- Anti-seize compound
- Safety glasses
- Gloves
Preparation
Before starting the installation, ensure that you have all the necessary tools and materials. It’s also important to prepare your workspace to make the process easier.
Make sure the car is parked on a flat surface and that the engine is cool. Wear safety glasses and gloves to protect yourself during the installation.
Step 1: Remove the Old Headers
Begin by disconnecting the battery to prevent any electrical issues. Next, lift the car using jack stands for better access to the exhaust system.
Locate the existing headers and remove the bolts connecting them to the engine. Use a socket set and wrench to carefully detach the old headers.
Once the bolts are removed, disconnect the exhaust from the headers. Be cautious as some bolts may be rusted or stuck; applying penetrating oil can help.
Step 2: Prepare the New Headers
Before installing the AEM headers, check the new headers for any defects or damages. Clean the mating surfaces using a gasket scraper to ensure a proper seal.
Apply a thin layer of anti-seize compound to the threads of the new bolts to prevent them from seizing in the future.
Step 3: Install the New Headers
Position the AEM headers in place and align them with the exhaust ports. Carefully insert the bolts and hand-tighten them to hold the headers in position.
Using a torque wrench, tighten the bolts to the manufacturer’s specified torque settings to ensure a secure fit. Refer to the AEM installation manual for specific torque values.
Step 4: Reconnect the Exhaust System
After the headers are securely installed, reconnect the exhaust system. Make sure all connections are tight and properly aligned.
Replace any old gaskets with new ones to prevent exhaust leaks. Ensure that the exhaust is securely fastened to the new headers.
Step 5: Reconnect the Battery and Test
Reconnect the battery and start the engine. Listen for any unusual sounds that might indicate a leak or improper installation.
Allow the engine to warm up and check for any exhaust leaks around the new headers. If everything sounds good, you are ready to take your Miata for a test drive!
Conclusion
Installing AEM headers on your Miata can be a rewarding project that enhances your vehicle’s performance. By following this step-by-step guide, even beginners can successfully complete the installation.
Always remember to take your time and double-check each step to ensure a successful installation.
