Preparation Steps
Before starting the installation, ensure that you have all the necessary tools and materials at hand. Additionally, make sure your vehicle is parked on a flat surface and that the engine is cool to avoid burns.
1. Safety First
Wear safety goggles and heat-resistant gloves to protect yourself during the installation process. It’s important to prioritize safety to prevent any injuries.
2. Lift the Vehicle
Using a jack, lift the front of the vehicle and secure it with jack stands. This will give you ample space to work underneath the car, especially for the exhaust system installation.
Installing the Greddy Intake System
Follow these steps to install the Greddy Intake System on your S14 240SX:
- Remove the engine cover by unscrewing the bolts.
- Disconnect the negative battery terminal to prevent any electrical issues.
- Unplug the mass airflow sensor (MAF) and any other sensors connected to the factory intake.
- Loosen the clamps holding the factory intake tube and remove it carefully.
- Remove the factory air filter box by unscrewing the bolts that secure it in place.
- Install the Greddy intake pipe by aligning it with the throttle body and securing it with the provided clamps.
- Attach the new air filter to the end of the intake pipe, ensuring it is tight and secure.
- Reconnect the MAF sensor and any other sensors you previously unplugged.
- Reinstall the engine cover and reconnect the negative battery terminal.
Installing the Greddy Exhaust System
Once the intake system is installed, you can proceed with the exhaust system installation:
- Locate the factory exhaust system starting from the catalytic converter.
- Use a socket set to remove the bolts securing the exhaust system to the catalytic converter.
- Carefully detach the exhaust hangers using a screwdriver or pry tool to free the exhaust system from the vehicle.
- Remove the entire factory exhaust system from the vehicle.
- Align the Greddy exhaust system with the catalytic converter and attach it using the provided hardware.
- Secure the exhaust system to the vehicle using the exhaust hangers, ensuring it is properly supported.

- Double-check all connections and ensure there are no leaks.
Final Checks and Testing
After both systems are installed, it’s important to conduct final checks before taking your car for a drive:
- Start the engine and listen for any unusual sounds that may indicate a problem.
- Check for any exhaust leaks around the connections.
- Ensure that all sensors are functioning correctly and that there are no warning lights on the dashboard.
- Take the vehicle for a short test drive to ensure everything is working as expected.
