How do I know a part will fit my Audi RS4?

Every car-specific part here is linked to the Audi RS4 (B9) in our vehicle list, which records fitment by model, chassis and year. Universal items are shown too and suit most cars. If you are unsure, our team can confirm fitment before you order, Monday to Friday, 9am to 5pm UK time.

Yes. UK delivery is free on orders over £99.
What is your returns policy?

You have 28 days from delivery to return a part: within that time, let us know and send it back to our warehouse. The full terms are in our refund policy.
Are parts covered by a guarantee?

Yes. Everything we sell carries a 6-month AUTOID guarantee, and many parts also carry the maker's own warranty, which varies by brand.

The B9 RS4 Avant swapped the old V8 for a twin-turbocharged V6, keeping the fast estate's understated character. It suits upgrades that add definition without overworking the design.

Here you will find the parts we have matched to the Audi RS4 (B9), covering 2018 to 2019 cars, alongside universal items that are not tied to one model. If you are unsure whether a part suits your car, our team can confirm fitment before you order.
