The Nissan 370Z is a beloved sports car known for its performance and handling. Many enthusiasts look for ways to enhance its power and efficiency. One common upgrade is the ignition coils, and HKS is a well-known brand in the aftermarket performance parts industry. This article explores whether upgrading to HKS ignition coils can truly boost your Nissan 370Z’s power by 20 horsepower.
Understanding Ignition Coils
Ignition coils play a critical role in the performance of an engine. They convert the battery’s low voltage into the high voltage needed to ignite the air-fuel mixture in the combustion chamber. A more efficient ignition coil can lead to better combustion, improved throttle response, and potentially more horsepower.
Why Upgrade to HKS Ignition Coils?
HKS ignition coils are designed to provide a stronger spark and improved reliability compared to stock coils. Here are some reasons why enthusiasts consider upgrading:
- Improved Spark Energy: HKS coils are engineered to deliver a more powerful spark, which can enhance combustion efficiency.
- Increased Reliability: High-quality materials and construction can lead to longer lifespan and better performance under high-stress conditions.
- Better Throttle Response: A stronger spark can improve engine responsiveness, making the car feel more lively on acceleration.
- Compatibility with Modifications: If you have made other performance upgrades, HKS coils can help maximize the benefits of those modifications.
Potential Power Gains
Many enthusiasts claim that upgrading to HKS ignition coils can yield significant power gains. However, the actual increase in horsepower can vary based on several factors, including:
- Engine Condition: A well-maintained engine is more likely to benefit from ignition upgrades.
- Other Modifications: If the car has other performance enhancements (like a cold air intake or exhaust), the gains may be more noticeable.
- Tuning: Proper tuning after installing new coils can help unlock their full potential.
- Driving Style: The way you drive can also impact how much you feel the difference in power.
Real-World Experiences
Many Nissan 370Z owners have shared their experiences after upgrading to HKS ignition coils. Here are some common observations from the community:
- Noticeable Throttle Response: Many drivers report a more responsive throttle, especially at higher RPMs.
- Improved Fuel Efficiency: Some users have noted better fuel consumption, suggesting more efficient combustion.
- Power Gains: While some report gains close to 20 horsepower, others see more modest increases, typically around 10-15 HP.
- Enhanced Engine Sound: Upgraded coils can lead to a more aggressive engine note, adding to the overall driving experience.
Installation Process
Installing HKS ignition coils in a Nissan 370Z can be done with basic tools and some mechanical knowledge. Here’s a brief overview of the installation process:
- Gather Tools: You will need a socket set, torque wrench, and possibly a flathead screwdriver.
- Remove Engine Cover: Start by removing any engine covers to access the ignition coils.
- Disconnect Electrical Connectors: Carefully disconnect the electrical connectors from the stock coils.
- Remove Stock Coils: Unscrew the bolts holding the stock ignition coils in place and remove them.
- Install HKS Coils: Place the HKS coils in the same position as the stock ones and secure them with bolts.
- Reconnect Electrical Connectors: Reattach the electrical connectors to the new coils.
- Test the Installation: Start the engine and ensure everything is functioning correctly.
Conclusion
Upgrading to HKS ignition coils can provide benefits such as improved throttle response, better fuel efficiency, and the potential for increased horsepower. While some users report gains close to 20 HP, results can vary based on the condition of the engine, other modifications, and tuning. For enthusiasts looking to enhance their Nissan 370Z, HKS ignition coils are certainly worth considering as part of a broader performance upgrade strategy.
