The Mazda Renesis engine, found in the RX-8, is known for its unique rotary design and high-revving capabilities. However, many enthusiasts seek to unlock more power from this already impressive engine. One of the most effective ways to achieve this is by upgrading to an AEM intake and exhaust system. This article will explore the benefits of these upgrades, potential power gains, and the overall cost-effectiveness of this modification.
Understanding the Renesis Engine
The Renesis engine is a naturally aspirated rotary engine that offers a unique driving experience. With its lightweight design and compact size, it provides a different approach to performance compared to traditional piston engines. However, like any engine, there is always room for improvement.
Benefits of Upgrading to AEM Intake and Exhaust
Upgrading to an AEM intake and exhaust system can significantly enhance the performance of your Renesis engine. Here are some key benefits:
- Increased Airflow: AEM systems are designed to improve airflow to the engine, allowing it to breathe better and produce more power.
- Weight Reduction: Aftermarket exhaust systems are often lighter than stock components, contributing to overall vehicle performance.
- Improved Throttle Response: Enhanced air intake leads to quicker throttle response, making the car feel more agile.
- Better Sound: AEM exhaust systems provide a more aggressive sound, enhancing the driving experience.
Expected Power Gains
Enthusiasts can expect power gains of approximately 15-20 horsepower with the installation of an AEM intake and exhaust system. These gains may vary based on the specific configuration of the vehicle and additional modifications. However, the improvements in horsepower and torque can be felt immediately.
Cost of Upgrading
One of the most appealing aspects of upgrading your Renesis with an AEM intake and exhaust system is the cost. Typically, these upgrades can be completed for under $1,000, making them a budget-friendly option for those looking to enhance their vehicle’s performance.
Breakdown of Costs
Here’s a rough breakdown of the costs associated with upgrading to an AEM intake and exhaust:
- AEM Cold Air Intake: $300 – $400
- AEM Cat-Back Exhaust: $500 – $600
- Installation (if not DIY): $100 – $200
Installation Process
Installing an AEM intake and exhaust system can be a rewarding DIY project. Here are the general steps involved:
- Gather Tools: You will need basic hand tools such as wrenches, screwdrivers, and possibly a torque wrench.
- Remove Stock Parts: Carefully remove the factory intake and exhaust components, taking care not to damage any surrounding parts.
- Install AEM Intake: Follow the instructions provided with the AEM intake kit to install the new components securely.
- Install AEM Exhaust: Similarly, install the AEM exhaust system, ensuring all connections are tight and leak-free.
- Test Drive: Once everything is installed, take your vehicle for a test drive to feel the improvements.
Conclusion
Upgrading your Renesis with an AEM intake and exhaust system is one of the best ways to enhance performance without breaking the bank. With power gains of 15-20 horsepower and a cost-effective price tag, this modification is a must for any RX-8 enthusiast looking to maximize their vehicle’s potential.
