Mazda RX8 Intake Upgrade: Boosting Performance and Power

Introduction

The Mazda RX8 is a high-performance sports car that has garnered attention for its unique rotary engine and sleek design. However, like any vehicle, it can benefit from upgrades to enhance its performance and power output. One of the most effective ways to improve the RX8's performance is by upgrading its intake system. In this article, we will explore the benefits of an intake upgrade and provide a step-by-step guide on how to install one.

Benefits of an Intake Upgrade

An intake upgrade offers several benefits for the Mazda RX8, including increased horsepower, torque, and fuel efficiency. By allowing more air into the engine, an upgraded intake system allows the rotary engine to breathe more efficiently, resulting in improved performance and power output. Additionally, an intake upgrade can also reduce the risk of engine knock or pinging, which is common in high-boost applications.

Types of Intake Upgrades

There are several types of intake upgrades available for the Mazda RX8, each with its own set of benefits and drawbacks. Some of the most popular options include:

1. Cold Air Intake (CAI): A CAI pulls in cooler air from outside the engine compartment, which is denser and contains more oxygen molecules than the warmer air inside the engine compartment. This results in a significant increase in power and torque.

2. Short Ram Intake (SRI): An SRI is designed to draw in air from within the engine compartment, but it is shorter and less restrictive than the stock intake system. This results in a smoother power curve and improved throttle response.

3. Injen Intake: An Injen intake is a hybrid between a CAI and an SRI. It pulls in air from both outside and inside the engine compartment, providing a balance between power and throttle response.

4. AEM Intake: An AEM intake is similar to a CAI but features a unique design that allows for better filtration and increased airflow. It is known for providing a significant increase in power and torque.

Tools and Materials Needed

Before starting the installation process, it is essential to have all the necessary tools and materials. These may vary depending on the type of intake upgrade you choose, but here are some common items you will need:

• New intake system (CAI, SRI, Injen, or AEM)
• Intake manifold gasket
• Throttle body gasket
• MAF sensor adapter (if applicable)
• Vacuum hose (if applicable)
• Hose clamps
• Socket set
• Torx screwdriver
• Pliers
• Wrenches
• Safety glasses
• Gloves

Installation Guide

The installation process for an intake upgrade can vary depending on the type of intake you choose, but here is a general guide that applies to most systems:

1. Remove the Stock Intake System

Begin by removing the stock intake system. Start by disconnecting the battery to prevent any accidental starts during the installation process. Next, remove the engine cover and any other components that may be in the way of the intake system.

2. Disconnect the Throttle Body

Disconnect the throttle body from the stock intake manifold. You will need to remove the bolts that hold it in place and gently pull it away from the manifold. Be careful not to damage the throttle body or the manifold during this process.

3. Remove the Stock Intake Manifold

Remove the stock intake manifold by disconnecting the bolts that hold it to the engine block. Gently lift the manifold away from the engine and set it aside.

4. Install the New Intake System

Install the new intake system by following the manufacturer's instructions. Typically, this involves attaching the intake manifold to the engine block using the provided bolts and gaskets. Make sure all connections are secure and properly sealed.

5. Reconnect the Throttle Body

Reconnect the throttle body to the new intake manifold. Make sure it is securely attached and properly aligned.

6. Reconnect the MAF Sensor

If your new intake system requires a MAF sensor adapter, install it now. Connect the MAF sensor to the adapter and ensure it is properly secured.

7. Reconnect the Vacuum Hose

If your new intake system requires a vacuum hose, connect it to the intake manifold and the throttle body. Make sure the hose is securely attached with hose clamps.

8. Reinstall the Engine Cover

Reinstall the engine cover and any other components you removed during the installation process.

9. Start the Engine and Check for Leaks

Start the engine and check for any leaks around the intake system. Listen for any unusual noises or vibrations, and make adjustments as necessary.

10. Tune the Engine

After installing the new intake system, it is recommended to have the engine tuned to optimize performance. This may involve adjusting the fuel injection system, ignition timing, and other parameters to ensure the engine is running at its best.

Conclusion

Upgrading the intake system on your Mazda RX8 is a great way to improve its performance and power output. By allowing more air into the engine, you can experience increased horsepower, torque, and fuel efficiency. With several types of intake upgrades available, including CAI, SRI, Injen, and AEM, you can choose the one that best suits your needs and preferences. Remember to follow the manufacturer's instructions and take necessary safety precautions during the installation process.
