Audi A4 B9 Tuning Parts

For the Audi A4 B9 2015–2024 (Sedan and Avant) there is model-specific RS4-style tuning: RS-Style and S-Style front bumpers, an RS4-Style body kit, a complete rear bumper assembly, hood, grilles, rear diffusers with exhaust tips, lip splitters, spoilers and side skirts, as well as floor mats, wind deflectors, mud flaps, chrome trim, mirror caps, roof cross bars and steering wheels. Front and rear parts are divided into pre-facelift 2015–2019 and facelift 2019–2024 — they are not interchangeable. The years are specified in the name of each product.

Which RS4-style body kit fits the A4 B9: pre-facelift or facelift?

The largest section is GT Tuning body kits and bumpers. For 2015–2019 there is an RS-Style front bumper, its “for radars” version (for cars with sensors in the bumper), and an S-Style bumper; for 2019–2024 — an RS-Style front bumper, a complete rear bumper assembly, and the full RS4-Style body kit set. All parts are plastic, mount to OEM locations, and are paint-ready: first test-fit and adjust gaps, then paint. You can install the kit at the network of DD Tuning certified service centers — your manager will advise the nearest one. For Allroad, compatibility of the RS-Style bumper is уточнюють separately: there may be differences in mounting points. For the front end: the RS-Style hood (2015–2019, metal), radiator grilles (RS-style Quattro is also compatible with the Sedan S-Line 2016–2019; rings and the license plate mount are as shown in the photos), and RS-Style fog light grilles (2 pcs), separately for each generation.

Lips, diffusers, spoilers and side skirts: plastic or carbon?

Lip splitters: DPT V-1 for the S-Line bumper 2015–2019 (gloss black, 174 cm) and V-1, V-2, V-3 for 2019–2024 — ABS plastic installed with automotive glass sealant/adhesive, which is not included. Rear diffusers: for 2015–2019 — S-Style and DPT (148 cm) for the standard bumper; for 2019–2024 — RS-Style V-1 and V-2 with exhaust tips, plus rear diffuser add-ons. Spoilers — DPT in gloss black (121 cm) and eight carbon options for the Sedan; side skirts DPT — a pair, 194 cm each, paint-ready. Real carbon is in the carbon trim section: lips, diffusers and fog light trims for Base and S-Line Sedan, RS4 Avant parts, and mirror caps.

Trunk mats — separately for Sedan and Avant: Carsuit, Stingray 3D, textile, and EVA in six colors. Also available: S-Style and R8-Style steering wheels and Omsa Line door sill plates for 4 doors.

Chrome, mirrors, wind deflectors, mud flaps, roof — what fits the Sedan and what fits the Avant?

RS-Look DPT mirror caps stick over the factory covers — no need to remove them; carbon caps V1 and V2 are also available. Stainless steel chrome trims: Carmos trunk edge trim (check the body type in the product card), Omsa Line trim above the plate — for Sedan, Carmos rear bumper trim 99 × 8 cm — for Avant. HIC wind deflectors — Sedan and Avant versions, 4 pcs. Premium mud flaps — 4 pcs, OEM mounting points, separately for 2015–2019 and 2019–2024; the second set also fits the 2022 Avant. For the Avant roof — cross bars for standard and integrated rails; for the Sedan smooth roof — a pair of Oluksuz V4. There are also A4 lettering and emblems.

How to choose the right part for your A4 B9

1. Years: 2015–2019 pre-facelift, 2019–2024 facelift — front and rear parts are not interchangeable.
2. Bumper: Base, S-Line, or an already installed RS-style bumper use different add-ons. If the bumper was replaced, go by the bumper you have, not the model year.
3. Body type and trim in the product card: Sedan and Avant differ in wind deflectors, trunk mats, and rear trims; adhesive for lips and side skirts is sold separately. Not sure? Send your manager a photo of the front or rear end.
