The BMW M4 Competition is known for its impressive performance, but enthusiasts often seek ways to enhance its power further. With the right intake and exhaust modifications, it’s possible to boost the horsepower from the stock 470 to over 520 hp. This article explores the best intake and exhaust mods for the M4 Competition.
Understanding the M4 Competition’s Engine
The M4 Competition is powered by a 3.0-liter BMW M TwinPower Turbo inline 6-cylinder engine. This engine is designed for high performance and efficiency, but there are always ways to unlock more potential.
Stock Performance Overview
The stock M4 Competition delivers 470 hp and 406 lb-ft of torque. While this is impressive, many drivers desire a more exhilarating experience. By upgrading the intake and exhaust systems, significant gains can be achieved.
Intake Modifications
Upgrading the intake system is one of the most effective ways to increase horsepower. A high-performance intake allows for better airflow, which can lead to improved combustion and power output.
- Cold Air Intakes: These intakes draw cooler air from outside the engine bay, increasing density and performance.
- High-Flow Filters: Replacing the stock air filter with a high-flow option can improve airflow and filtration.
- Intake Manifold Upgrades: An aftermarket intake manifold can enhance airflow distribution to the cylinders.
Exhaust Modifications
Aftermarket exhaust systems can significantly enhance the M4 Competition’s sound and performance. A less restrictive exhaust allows for better airflow, reducing back pressure and increasing horsepower.
- Cat-Back Exhaust Systems: These systems replace the factory exhaust from the catalytic converter back, providing a more aggressive sound and improved performance.
- Downpipes: Upgrading to high-flow downpipes can help reduce turbo lag and increase power.
- Exhaust Tips: While they may not provide significant performance gains, they can enhance the aesthetic appeal and sound of the exhaust.
Combining Intake and Exhaust Mods
For optimal performance, combining both intake and exhaust modifications is crucial. This synergy allows for maximum airflow and efficiency, resulting in a more powerful engine.
Expected Power Gains
With the right combination of intake and exhaust mods, M4 Competition owners can expect power gains of 50 hp or more. This can elevate the total output to over 520 hp, providing an exhilarating driving experience.
Considerations Before Modifying
Before diving into modifications, it’s essential to consider a few factors to ensure a successful upgrade:
- Warranty Implications: Modifying your vehicle can void warranties, so check with your dealer.
- Installation: Professional installation is recommended for complex systems to ensure proper fitment and performance.
- Tuning: After modifications, an ECU tune may be necessary to maximize performance and efficiency.
Conclusion
Enhancing the BMW M4 Competition’s horsepower from 470 to over 520 hp is achievable through carefully selected intake and exhaust modifications. By understanding the benefits of these upgrades and considering the necessary factors, enthusiasts can enjoy a thrilling driving experience with their M4.
