As a proud owner of an Infiniti G37, I can confidently say that the rear diffuser is an essential component for both performance and aesthetics. This sleek addition not only enhances the overall look of the vehicle, but also plays a crucial role in its functionality.

Firstly, the rear diffuser helps to improve the car’s aerodynamics. By creating a low-pressure area under the vehicle, it allows air to flow smoothly and efficiently underneath, reducing drag and increasing stability. This becomes particularly important at high speeds, where even small differences in aerodynamics can make a significant impact on performance.

Moreover, the diffuser also works to optimize airflow around the exhaust system. It helps to create a vacuum that pulls hot air away from the engine and exhaust pipes, thus reducing heat build-up and improving overall engine performance. This is especially beneficial for those who enjoy pushing their G37 to its limits on track days.

Aside from its functional benefits, the rear diffuser also adds a touch of sportiness and aggression to the car’s appearance. Its sleek design complements the already stylish body of the G37, giving it a more race-inspired look. It also serves as a subtle reminder that this is not just any ordinary luxury sedan – it’s a true performance machine.

In conclusion

My Buying Guide on ‘Infiniti G37 Rear Diffuser’

As a proud owner of an Infiniti G37, I have always been on the lookout for ways to enhance its appearance and performance. One major upgrade that I highly recommend is installing a rear diffuser. Not only does it give your car a more aggressive and sporty look, but it also improves its aerodynamics and overall handling. In this buying guide, I will share my experience and provide useful tips for purchasing the perfect rear diffuser for your Infiniti G37.

1. Know Your Needs

The first step in purchasing an Infiniti G37 rear diffuser is to determine your specific needs. Are you looking for a purely aesthetic upgrade or do you want to improve your car’s performance? Different rear diffusers offer different benefits, so it’s important to know what you’re looking for.

Each brand has its own unique design and features, so make sure to read reviews and compare prices before making a decision.

3. Consider Material and Fitment

Rear diffusers are typically made from either carbon fiber or polyurethane (PU) material.

Installing a rear diffuser may require some modifications or drilling on your car’s bumper. Some brands offer easy DIY installation while others may require professional installation. Make sure to check the installation instructions before purchasing to avoid any surprises.

5. Set a Budget

Rear diffusers come in a wide range of prices depending on the brand, material, and design. It’s important to set a budget beforehand so you don’t overspend or compromise on quality.

6. Read Customer Reviews

Customer reviews are an excellent way to gauge the quality and effectiveness of a product. Make sure to read reviews from other Infiniti G37 owners who have installed the same rear diffuser model that you’re considering.

7. Consider Warranty and Return Policy

In case of any defects or issues with your rear diffuser, it’s important to check the warranty coverage and return policy offered by the brand or retailer.
