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.
