370Z Cold Air Intake 101

370Z Cold Air Intake: What It Does

Engines work by sucking oxygen, mixing the air with fuel, and then burning this mixture for power production. It needs a proper amount of air and better airflow to “breathe” which is where the cold air intake system comes in.

The cold air intake’s main purpose is to bring cool air to the vehicle’s internal-combustion engine. It’s installed in a way that the system moves air filters outside the engine compartment, allowing the engine to suck in cooler air for combustion which is important because the air is denser when colder, so the engine can get more oxygen in even in smaller volumes.

Furthermore, the system helps in lessening hot air on the engine and reducing the air temperature which would increase the airflow within the compartment. By reducing airflow resistance, it also reduces the unwanted turbulence in engine pipes.

Combining both features can allow your engine to provide maximum horsepower. It can also increase the car’s fuel efficiency and overall performance in the long run!

There are many other ways to increase airflow to your engines, like superchargers or turbochargers. However, using a cold air intake system is the most cost-efficient and easiest. It’s recommended for those who want to save time and money on installation and still get similar results.

How Much Horsepower in 370Z With Cold Air Intake?

The amount of horsepower your Nissan 370Z engine can provide with the cold air intake system depends on a couple of factors:

  • year of the model;
  • quality.

In general, all of the Nissan 370Z V6 engines produce up to 332 hp and offer 260 lb. ft. of torque. When using a cold air intake system, it can add up to 18 hp and 6 lb. ft. When added up, your engine will be able to run on 350 hp and 266 lb. ft. which is a great number that may grow as you continue to make the right modifications for your Nissan.

Cold Air Intake for an Automatic 370Z

What’s great about cold air intake systems is that they are installed straight on the car’s engine. Meaning the system has nothing to do with the car’s gearbox and with other mechanical systems inside.

Because of that, all cold air intake systems would fit either a manual or automatic gearbox. The increased engine performance is similar regardless of what gearbox type the car uses.

As long as it’s installed correctly and suits your Nissan 370Z model, I don’t see why there would be a problem with the type of gearbox used upon installation. You can refer to the reviews I have mentioned above to see which cold air intake system meets both you and your engine’s specific needs.


Cold air intake system installation is similar throughout all car models, and what’s great about these systems is that they’re extremely easy to install. You cut costs on installation because you can finish it within a day and do it yourself. With the right tools and knowledge about your car engine and the system, it can take about an hour and a half to install.

Here are some quick tips to help you go through the cold air intake installation process yourself:

  1. Make sure the engine is switched off and the car battery is unplugged. Allow the engine and its parts to cool down before installation.
  2. Take off the built-in air intake system by removing the filter, its box, and the pipe that leads to the engine. If it’s on the engine, use your socket set to remove its bolts. Also, remove the sensors on the old intake, if there is.
  3. Fit in your new cold air intake system according to instructions given. This depends on the type and brand of system you get.
  4. After you’ve attached everything and have the cold air intake connected to the engine, check what you’ve accomplished. The intake pipe should be running away from the car’s engine bay and runs from the throttle bay. Check if all mountings are tightened and secure enough.
  5. Now reattach the car battery terminal and run a test drive to see if everything is working well. That’s it!

Horsepower Amount for 370Z

The Nissan 370Z is a sports coupe with an amazing engine, new and improved from its predecessors. It dons the V6 engine, coming with a displacement of 3.7L and producing 332 horsepower in the 370Z’s base level. That’s already powerful enough, with a cold air intake system being able to add in more power to that with its efficient purpose!

The extra horsepower added will depend on the cold air intake system you get and the 370Z model you own. On average, the system will be able to add up to an estimate of 15 horsepower on standard 2009-2017 Nissan 370Zs. I don’t have the exact numbers available, but reports show that the number can even exceed 18 horsepower. Besides the horsepower, it can also increase your torque by up to 6 ft. lbs.


Cold air intakes for 370Z are extremely advantageous and offer better engine performance in the long run. As long as you’re able to purchase the right one and properly install it, you won’t have any issues and focus on your ride.

I hope that this article on the best cold air intake for 370Z helps you out. So don’t waste your time and choose the right product for you!
