The Plymouth Road Runner is a classic muscle car that has captured the hearts of enthusiasts for decades. With its powerful engine and sleek design, it has become a symbol of American automotive performance. However, to truly maximize its potential, many owners seek to enhance their vehicle’s power output. In this article, we will explore the top cold air intake and exhaust upgrades that can help you achieve over 400 horsepower in your Plymouth Road Runner.
Understanding Cold Air Intakes
A cold air intake system is designed to improve an engine’s airflow, allowing it to breathe better and produce more power. By drawing in cooler air from outside the engine bay, these systems can significantly increase horsepower and torque. When considering upgrades for your Plymouth Road Runner, a high-quality cold air intake is essential.

Combining Cold Air Intake and Exhaust Upgrades
For optimal performance, it is recommended to combine both cold air intake and exhaust upgrades. This combination allows for maximum airflow into and out of the engine, resulting in significant power gains. When both systems work in harmony, you can expect to see improvements in horsepower, torque, and overall driving experience.
- Synergistic Effects:
- Increased overall engine efficiency.
- Enhanced performance across the RPM range.
- Better engine responsiveness and acceleration.
- Recommended Combinations:
- K&N Cold Air Intake with Flowmaster Exhaust.
- BBK Cold Air Intake with Borla Exhaust.
- Spectre Cold Air Intake with MagnaFlow Exhaust.
Installation Tips and Considerations
Installing a cold air intake and exhaust system can be a rewarding DIY project, but it’s essential to follow proper procedures to ensure a successful upgrade. Here are some tips to keep in mind during installation:
- Preparation:
- Gather all necessary tools and materials before starting.
- Read the installation instructions thoroughly.
- Safety First:
- Always wear protective gear, including gloves and safety glasses.
- Work in a well-ventilated area to avoid inhaling fumes.
- Testing:
- After installation, start the engine to check for any leaks or issues.
- Take the vehicle for a test drive to feel the performance changes.
Conclusion
Maximizing the power of your Plymouth Road Runner is an exciting journey that involves careful selection of upgrades. By investing in quality cold air intake and exhaust systems, you can unlock the full potential of your muscle car, achieving over 400 horsepower. With the right combination of parts and proper installation, your Road Runner will not only perform better but also provide an exhilarating driving experience.
