The Nissan 370Z is a popular sports car known for its performance and sleek design. One of the most common modifications enthusiasts make to enhance its power is installing a cold air intake. Among the most popular options are K&N and AEM cold air intakes. This article will compare these two brands to determine which one adds more power to your Nissan 370Z.
Understanding Cold Air Intakes
Cold air intakes are designed to improve engine performance by allowing cooler air to enter the engine. Cooler air is denser than warm air, which means it contains more oxygen. More oxygen allows for better combustion, resulting in increased horsepower and torque. Both K&N and AEM have developed their own technologies to enhance air intake efficiency.
K&N Cold Air Intakes
K&N has been a leader in the performance air filter industry for decades. Their cold air intakes are known for their high-flow design and reusable filters. Here are some key features of K&N cold air intakes:
- High-Flow Air Filters: K&N filters are designed to provide maximum airflow while filtering out contaminants.
- Easy Installation: Most K&N intakes can be installed with basic tools and do not require any permanent modifications to the vehicle.
- Durable Construction: Made from high-quality materials, K&N intakes are built to last and withstand harsh conditions.
- Emissions Legal: Many K&N intakes are street legal and comply with emissions regulations.
Performance Gains with K&N
Users of K&N cold air intakes often report noticeable performance gains. On average, a K&N intake can add around 10-15 horsepower to the Nissan 370Z. Additionally, users frequently mention improvements in throttle response and engine sound.
AEM Cold Air Intakes
AEM is another well-respected brand in the performance intake market. They offer a variety of cold air intakes designed to maximize airflow and engine performance. Here are some notable features of AEM cold air intakes:
- Aluminum Construction: AEM intakes are often made from lightweight aluminum, reducing weight while maintaining strength.
- Increased Airflow: AEM designs focus on optimizing airflow with smooth bends and larger diameter tubing.
- Dry Flow Filter Technology: AEM’s filters do not require oiling, making maintenance easier for users.
- Street Legal Options: AEM also offers models that comply with emissions regulations.
Performance Gains with AEM
AEM cold air intakes are known for their performance enhancements as well. Users typically see gains of around 12-18 horsepower on the Nissan 370Z. The improved airflow can lead to a more aggressive engine sound and better overall performance.
Comparing Power Gains
When comparing the power gains from K&N and AEM cold air intakes, it is essential to consider various factors, including installation, driving conditions, and vehicle modifications. Here’s a quick comparison:
- K&N: Typically adds 10-15 horsepower.
- AEM: Generally adds 12-18 horsepower.
Installation Process
Both K&N and AEM cold air intakes are designed for easy installation. However, there are slight differences in their installation processes:
- K&N: Usually requires minimal tools and can be completed in about an hour.
- AEM: Also designed for straightforward installation, but some models might take slightly longer due to additional components.
Maintenance and Longevity
Maintenance is crucial for ensuring the longevity and performance of cold air intakes. Here’s how K&N and AEM stack up:
- K&N: Filters are reusable and can be washed and re-oiled, but require regular maintenance.
- AEM: Dry flow filters do not require oiling, making them easier to maintain.
Cost Considerations
Cost is always a factor when considering upgrades. Here’s a general price comparison:
- K&N: Prices typically range from $300 to $400.
- AEM: Prices usually range from $250 to $350.
User Reviews and Feedback
User feedback is invaluable when comparing products. Here’s a summary of common sentiments:
- K&N: Users appreciate the noticeable power increase and the sound improvement.
- AEM: Users often highlight the ease of installation and the no-oil maintenance feature.
Conclusion
Both K&N and AEM cold air intakes offer significant performance enhancements for the Nissan 370Z. The choice between the two may ultimately come down to personal preference, budget, and maintenance considerations. If you prioritize ease of maintenance, AEM might be the better choice. Conversely, if you are looking for a well-established brand with a proven track record, K&N is an excellent option. Regardless of your choice, both intakes will enhance your driving experience.
