Frequently Asked Questions

What is a wheel lug bolt cap and why do I need one?

A lug bolt cap is a small protective cover that fits over the threaded end of your wheel's lug bolt. It shields the bolt threads from moisture, road salt, and corrosion while giving your wheels a finished, factory appearance. If a cap is missing or damaged, replacing it prevents rust from forming on the bolt threads, which can make wheel removal difficult during future tire service.

How many lug bolt caps do I need for my Audi?

Most Audi vehicles use five lug bolts per wheel, meaning you need five caps per wheel. For a complete set across all four wheels, order 20 caps. If you are replacing only missing or damaged caps, count the number needed and order accordingly.

Will this Genuine OEM cap fit my 2023 Audi S5?

Yes. The Genuine OEM 4M0601173D cap is designed for the B9 S5 across all model years from 2018 through 2024. Use the vehicle selector tool above to confirm your exact trim and year for absolute fitment certainty.

Can I install this cap myself?

Yes. Lug bolt caps are simple push-fit components with no tools required. Simply press the cap straight onto the threaded end of each lug bolt until it seats fully. No torque wrench, special tools, or professional installation is necessary.

What is the difference between this Genuine OEM cap and an aftermarket alternative?

Genuine OEM Audi parts are engineered and tested by the manufacturer to exact specifications, ensuring perfect fit and finish on your vehicle. They carry the factory warranty and are the same parts used on the assembly line. Aftermarket caps may vary in material quality, fit, and longevity. For wheels and visible components, many owners prefer the assurance of genuine parts.

Do I need to replace lug bolt caps regularly?

Lug bolt caps are durable and typically last the life of your vehicle. However, they can be lost due to impact, vibration, or wheel removal during tire service. Inspect your caps whenever you have your wheels off the vehicle, and replace any that are cracked, missing, or damaged to prevent corrosion on the underlying bolts.

Order Genuine OEM 4M0601173D lug bolt caps today. In-stock orders ship same or next business day from our U.S. warehouse, and our fitment team is one call away if you need help confirming the right part for your Audi.
