2013–2016 Audi A3 / S3 / RS3 8V Sportback Rear Bumper Diffuser – Carbon Fiber
Enhance the rear styling of your Audi A3, S3, or RS3 8V Sportback with this carbon fiber rear bumper diffuser. Precision-molded to follow the factory bumper contours, it creates a lower, wider visual stance for a sharper, more performance-inspired rear end while keeping the clean lines of the original design.
Build
- Material: Genuine carbon fiber with an exposed weave, lightweight and durable
- Surface finish: High-gloss polished UV-resistant clear coat that showcases the carbon weave and protects it against fading and long-term surface degradation
- Configuration: Single-piece diffuser for the lower rear bumper
Design & Aerodynamics
- Aggressive stance: Diffuser profile creates a lower, wider visual stance for a sportier rear end
- Carbon aesthetic: Exposed weave and high-gloss polished finish deliver a motorsport-inspired look that complements the factory 8V design language
- Factory-style integration: Precision-molded to the contours of the factory rear bumper for a clean, seamless fit

Package Contents
- 1 × carbon fiber rear bumper diffuser
- Installation hardware
Installation
- Screw and adhesive mounted: Secures using both mounting screws and adhesive for a rigid, long-lasting fit
- Drilling required: Screw fixing pierces the bumper, so this is a permanent modification rather than a reversible fit
- Surface prep: Thoroughly clean, degrease, and dry the rear bumper before installation to ensure maximum adhesion and correct panel seating
- Alignment: Dry-fit and check the diffuser sits centred and even across the bumper before driving any screws
- Professional installation recommended for correct positioning, panel alignment, and a clean finish
Before You Install
- This is a permanent, screw-mounted fitment — confirm placement carefully before driving any screws, as holes cannot be undone
- Confirm your car is an 8V Sportback before ordering — this will not fit the Sedan or the later 8Y generation
- Verify your rear bumper shape against the product images before ordering — bumper detailing differs between trim levels
- Take care when parking rear-in — lower rear panels sit close to kerbs and parking blocks

FAQs
Please read our FAQs page to find out more.
Are OEM products more expensive than aftermarket alternatives?

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.
Can I purchase OEM parts online or do I need to visit a dealership?
You don’t need to visit a dealership to get OEM parts. You can conveniently purchase genuine OEM components from authorized distributors and reputable online retailers like Turbo Tech Performance. Our online store provides a wide selection of high-quality parts delivered straight to your door.

No, parts from Mopar, ACDelco, and Motorcraft are typically designed for specific vehicle brands. It’s crucial to ensure compatibility with your vehicle’s make and model by checking part numbers and consulting with a knowledgeable expert.
Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
Do OEM parts come with a warranty?
Yes, many OEM auto parts come with a manufacturer’s warranty that covers defects or issues. Be sure to check the warranty details for each part at the time of purchase, and keep your receipt for any potential warranty claims.
