Understanding Rear Diffusers

What is a Rear Diffuser?

A rear diffuser is a component of a vehicle’s underbody that helps to manage airflow as it exits the back of the car. By creating a low-pressure area, diffusers reduce drag and increase downforce, which can enhance the vehicle’s stability at high speeds.

How Do They Work?

The design of a rear diffuser allows air to flow more smoothly from the undercarriage of the vehicle. As the air passes through the diffuser, it expands and slows down, which decreases pressure and helps to pull the vehicle down toward the road. This aerodynamic effect is crucial for performance vehicles like the Infiniti G37.

Benefits of Installing a Diffuser

1. Improved Aerodynamics: Rear diffusers significantly enhance the car’s aerodynamic properties, reducing drag and increasing fuel efficiency.
2. Increased Downforce: By lowering the pressure under the car, diffusers help keep the vehicle grounded, providing better traction and stability.
3. Enhanced Aesthetic Appeal: A diffuser adds an aggressive look to your G37, making it stand out on the road.
4. Customizability: Diffusers come in various materials and finishes, allowing you to customize your vehicle’s appearance.

Types of Diffusers Available

Carbon Fiber Diffusers

Carbon fiber diffusers are among the most popular choices for G37 owners. They are lightweight yet extremely strong, providing excellent performance without adding unnecessary weight to the vehicle. Brands like Ahacarbon and AutoKits X offer high-quality carbon fiber diffusers that not only perform well but also look stunning.

Fiberglass Diffusers

Fiberglass diffusers are another option, often being more affordable than their carbon fiber counterparts. While they may not be as lightweight, they are still effective in improving aerodynamics. AutoCity Imports and Southbay Autoworkz both offer fiberglass options for the G37 sedan.

Honeycomb and Other Designs

Some diffusers feature unique designs, such as honeycomb patterns, which not only enhance aesthetics but also improve airflow. This design can be found at EzSplitters and other aftermarket suppliers.

Key Features to Consider

When selecting a rear diffuser for your G37 sedan, consider the following technical features:

Material

The material of the diffuser greatly affects its performance and weight. Carbon fiber is preferred for its strength-to-weight ratio, while fiberglass offers a budget-friendly alternative.

Fitment

Ensure that the diffuser is specifically designed for the G37 sedan to guarantee proper fitment. Brands like Outcast Garage and nextlevelperf.com focus on OEM fitment for their products.

Aesthetic Appeal

Consider the design and finish of the diffuser. Whether you prefer a gloss black finish or a raw carbon look, options abound from various suppliers.

Price

Prices for G37 diffusers can range from $285 to over $300, depending on the material and brand. Evaluate your budget and choose accordingly.
