Upgrading your intake system offers numerous benefits, including but not limited to, better air flow, more horsepower, better throttle response, and even potential fuel efficiency gains. These benefits provide a noticeably better driving experience, especially when pushing your car to its limits.
While performance gains are often the primary focus, a more efficient intake system can also lead to better fuel economy. By optimizing the air-to-fuel ratio, your engine can do more with less, thereby saving fuel over the long run.
A short ram intake is characterized by its short pipe length and proximity to the engine. Because of its design, it can pull in a large volume of air but is often exposed to the engine's heat.
On the upside, short ram intakes are relatively inexpensive and easier to install. They are great for quick throttle responses, making them suitable for city driving conditions. However, they have the drawback of often pulling in hot air from the engine bay, which is not as efficient for combustion as cooler air would be.
If you're primarily driving in the city and are looking for a quick and easy upgrade to boost throttle response, then a short ram intake would be a good choice for you.
Unlike the short ram intake, a cold air intake is designed to pull air from outside the hot engine bay into the intake tract. This ensures that the air entering the engine is cooler, which is beneficial for combustion efficiency.
Cold air intakes are generally more efficient than short ram intakes and provide a noticeable improvement in horsepower and torque. They are especially beneficial for high-speed driving where maximum power output is essential. However, they are usually more expensive and can be more complicated to install.
If you're doing a lot of highway driving or plan to take your Nissan 370Z to the track, a long tube cold air intake would be your best bet.
To install your new intake system, you'll typically need a basic set of hand tools like a screwdriver, a wrench set, and pliers.
Installing an intake system usually involves the following steps:
Always make sure the car is turned off and the engine is cool before starting any installation. Disconnect the battery to prevent any electrical issues.
The frequency of cleaning your intake system will depend on the type of filter it uses. Some filters require cleaning every 15,000 miles, while others can go up to 100,000 miles. Always refer to the manufacturer's guidelines for proper maintenance.
Should any part of your intake system fail or show signs of wear, it's crucial to replace it with parts that are up to the manufacturer's specifications. This ensures that the system continues to operate at peak efficiency.
If you notice a reduction in horsepower, a decrease in fuel efficiency, or unresponsiveness when you hit the throttle, these could be signs that your intake system is failing and needs attention.
So you've reached the end of our in-depth guide on finding the ideal cold air intake for your Nissan 370Z. Based on our analysis, the top options are the Stillen Ultra Long Dual Intake for its massive gains, the K&N Performance Intake Kit for its reputable quality, and the AEM Cold Air Intake for its balanced airflow improvements. Any of these intakes will have your Z breathing easier and making more power.
But an intake upgrade is just one part of building your ideal high-performance 370Z. Be sure to check out our other mod guides like our 370Z Exhaust Guide for increased airflow out, the comprehensive 370Z Tuning Guide to improve overall performance, the 370Z Coilover Guide for better driving dynamics, and the 370Z Turbocharger Guide or 370Z Supercharger Guide if big power is your goal.
Upgrading to a cold air intake system is one of the best first mods you can make to your Nissan 370Z. The VQ37HR was designed to perform and feeding it more air is an easy way to add more horsepower. With the right intake, you'll feel the power gains in the seat of your pants while putting a smile on your face. Choose wisely and get ready to experience your 370Z on a whole new level!
Absolutely, especially if you're looking to gain more power, better fuel efficiency, and a more responsive throttle.
Short ram intakes are easier to install and better for quick throttle response, whereas cold air intakes are more efficient and provide better performance gains, especially at high speeds.
The cleaning frequency varies based on the type of filter your system uses. Always consult the manufacturer's guidelines.
Most aftermarket intake systems are designed to comply with emissions regulations, but it's always a good idea to check your local laws to ensure that your new system is legal for road use.
For the Nissan 370Z, an intake system upgrade generally enhances fuel efficiency. However, the actual gains can vary depending on driving conditions and the specific intake system you choose. For instance, a cold air intake system that improves the air-fuel mixture can help your 370Z achieve better miles per gallon.
The Nissan 370Z is generally receptive to intake upgrades, but if you own a Nismo version, some intake systems may require slight modifications for a perfect fit. Always check the compatibility of the intake system with your specific 370Z model, including the year and any existing modifications.
While an upgraded intake system can improve performance metrics like horsepower and torque, its impact on resale value is generally neutral. Some buyers may appreciate the upgrade, but others might prefer a stock setup. Be sure to keep all original parts in case a future buyer wants the option to revert to the factory setup.
An intake upgrade can result in a more aggressive engine sound, especially during acceleration. If you enjoy a throaty engine growl, you'll likely appreciate the auditory effects of an upgraded intake on your 370Z.
Most of the intake systems designed for the Nissan 370Z are built to work well with the car's stock ECU settings. However, for maximum performance gains, you might consider a professional tune to ensure the engine is optimized to work with the new intake.
