So, you're looking to seriously upgrade your Nissan 370z, huh? Well, you've landed in the right spot! We're diving deep into the world of performance enhancements, specifically focusing on the PSE intake system and how it can catapult your Z to the next level. Guys, get ready to boost that horsepower and torque, because we're about to get technical – but don't worry, I'll keep it nice and easy to understand.

Why Upgrade Your 370z's Intake?

Let's start with the basics. What's the big deal about upgrading your intake anyway? The factory intake on the 370z, while decent, is designed with mass production and cost in mind. This means it often has restrictions that limit the engine's ability to breathe freely. Think of it like trying to run a marathon while breathing through a straw – not exactly optimal, right?

Upgrading your intake, especially with a high-performance system like the PSE intake, opens up the airflow, allowing your engine to inhale more air. This increased airflow translates directly to more power. When your engine gets more air, it can burn more fuel, resulting in a bigger explosion in the cylinders and, ultimately, more horsepower and torque. Plus, a better-designed intake can smooth out the airflow, reducing turbulence and improving the engine's overall efficiency. Beyond just raw power, an aftermarket intake can drastically improve throttle response and overall driving enjoyment. The engine feels more eager, more responsive to your inputs, and generally more alive. It's a difference you can feel every time you put your foot down. Lastly, let's not forget about the sound! A performance intake typically adds a more aggressive and throaty sound to your engine, making your 370z sound as good as it performs. All these benefits together make for a significantly enhanced driving experience, turning your already awesome 370z into an absolute beast on the road or track. With the right intake, you're not just adding power; you're unlocking the true potential of your engine and making every drive an exhilarating experience.

What Makes the PSE Intake Special?

Okay, so we know why upgrading your intake is a good idea. But why choose the PSE intake over the countless other options on the market? Well, PSE (which likely stands for Performance Systems Engineering, or something similar) intakes are designed with a specific focus on maximizing airflow and minimizing restrictions. They often use high-quality materials like mandrel-bent aluminum or carbon fiber to ensure smooth, consistent airflow and to reduce heat soak. Many PSE intakes feature larger diameter tubing compared to the stock intake, allowing for a greater volume of air to enter the engine. This increased volume, combined with a smoother flow path, can lead to significant gains in horsepower and torque, especially in the mid-range and top-end of the RPM range. PSE intakes also typically include high-flow air filters, which provide superior filtration while also allowing for increased airflow compared to the restrictive paper filters used in many stock intakes. The design and material choices used in PSE intakes contribute to maintaining lower intake air temperatures (IATs). Lower IATs mean denser air, which translates to better combustion and more power. Some PSE intake designs incorporate heat shields or enclosed airboxes to further minimize heat soak from the engine bay, ensuring that the air entering the engine is as cool as possible.

Beyond the performance benefits, PSE intakes are often designed for easy installation, utilizing existing mounting points and requiring minimal modifications to the vehicle. The result is a noticeable improvement in engine performance, a more aggressive engine sound, and a sleek look under the hood. So, if you are looking for an intake that provides a good balance of performance, quality, and ease of installation, the PSE intake is a great choice.

Expected Performance Gains

Alright, let's talk numbers. What kind of power gains can you realistically expect from installing a PSE intake on your 370z? While the exact numbers will vary depending on your specific setup, other modifications, and the dyno used for testing, you can generally expect to see gains in the range of 10-15 horsepower and 10-15 lb-ft of torque. Now, that might not sound like a huge amount, but remember that these gains are across the entire RPM range, not just at peak horsepower. This means you'll feel the difference in everyday driving, with improved throttle response and acceleration. One of the most noticeable improvements you will experience is enhanced throttle response. The engine will react more quickly and precisely to your inputs, making the car feel more lively and connected. This is particularly noticeable in situations where you need immediate power, such as merging onto a highway or overtaking another vehicle. The improved airflow also helps the engine breathe more efficiently at higher RPMs, allowing it to maintain power further up the rev range. This translates to stronger acceleration and a more exhilarating driving experience. On the dyno, these improvements typically show up as a flatter torque curve and a higher horsepower peak.

Furthermore, the enhanced engine sound that comes with a PSE intake adds to the overall sense of improved performance. The more aggressive intake noise makes the car feel faster and more powerful, even if the actual gains are relatively modest. Remember that these gains are often just the starting point. When combined with other modifications, such as an exhaust system, headers, and a tune, the PSE intake can contribute to even greater overall performance improvements. The intake provides the foundation for increased airflow, which allows the other modifications to work more effectively. Ultimately, the expected performance gains from a PSE intake on your 370z are a combination of increased power, improved throttle response, enhanced engine sound, and a solid foundation for further modifications. These factors together make it a worthwhile upgrade for any 370z owner looking to improve their car's performance and driving experience.

Installation: Is It a DIY Job?

So, you're sold on the PSE intake. Now comes the question: can you install it yourself, or do you need to take it to a professional? The answer, like most things, depends on your mechanical skill level and comfort zone. Generally speaking, installing an intake is a relatively straightforward process that most mechanically inclined individuals can handle with basic tools. The PSE intake is designed to be a direct replacement for the stock intake, meaning it should bolt right in without any major modifications. However, there are a few things to keep in mind.

First, you'll need to have a basic set of tools, including sockets, wrenches, screwdrivers, and pliers. You'll also want to have some penetrating oil on hand in case any of the bolts are seized. Before you start, it's always a good idea to disconnect the negative terminal of your battery to prevent any electrical issues. The installation process typically involves removing the stock intake system, which may require disconnecting some sensors and hoses. Be sure to take pictures or make notes as you go so you can remember how everything goes back together. Once the stock intake is removed, you can begin installing the PSE intake. This usually involves attaching the intake tube to the throttle body, connecting the air filter, and securing everything in place with clamps and brackets. Pay close attention to the instructions provided with the intake to ensure that everything is installed correctly. After the installation is complete, double-check all your connections and make sure everything is tight. Then, reconnect the battery and start the engine. Listen for any unusual noises or leaks. If everything sounds good, take the car for a test drive and enjoy the added performance! If you're not comfortable working on your car or if you run into any issues during the installation, it's always best to take it to a professional mechanic.
