10 Best Accessories For Audi A4 2026 in the United States

The MAXLINER Floor Mats are a solid choice for anyone looking to protect their 2017-2022 Audi A4, S4, or A4 All-Road's carpet. These mats fit all models and are designed to offer comprehensive coverage with their precisely molded, low-density material. One of the standout features is their all-weather, stain-resistant protection, making them ideal for any environment—whether dealing with snow, mud, sand, or salt water.

The custom fit, thanks to advanced vehicle scanning technology, ensures that your car's carpeting is well-protected from spills and messes. Additionally, these mats are easy to clean, as they can be hosed off or spot-cleaned with a damp cloth and soap, helping to maintain your car's interior aesthetic with their sleek, skid-resistant design. Being eco-friendly is another plus, as they are made from 100% recyclable materials and are odorless, which can be a big advantage for those sensitive to smells.

On the downside, these mats might be a bit bulkier than some other options (weighing 8.38 pounds), and some users may find their size (36 x 28 x 5 inches) slightly challenging to handle during installation or removal. If you're looking for durable, easy-to-maintain floor mats that are environmentally friendly and perfectly tailored for your Audi A4, these should serve you well.

The MCARCAR KIT A4 Carbon Fiber Rear Diffuser is a specialized accessory designed specifically for Audi A4 B9 Base Sedan 4Door models from 2017 to 2019. This rear diffuser is crafted from high-quality 3K carbon fiber, which is known for its strength, lightweight properties, and durability. The finish is polished and shiny, with a UV-protected clear coating to prevent fading over time.

Installation involves replacing the factory bumper diffuser and using screws, which may require professional assistance for a secure and precise fit. This diffuser not only enhances the car’s visual appeal by giving it a more sporty and distinct look but also offers functional benefits such as protecting the original rear lip from scrapes, bumps, and curbs.

Additionally, it provides aerodynamic advantages by adding downforce, detaching airflow, and improving stability, which can contribute to reduced fuel consumption. However, it is worth noting that this product is not compatible with A4 Sline and S4 models, so potential buyers should confirm fitment with the manufacturer before purchasing. Considering its premium material and the specific fit for certain Audi models, this rear diffuser is ideal for Audi A4 B9 Base Sedan owners looking to boost both style and function.
