Audi A4 (B9) Tuning & Performance Parts

The B9 A4 is a good car to tweak because even small changes can make a real difference to how it looks and feels on the road. At Awesome GTI, you’ll find Audi A4 B9 mods for the way the car sits and looks, with parts matched to the B9 rather than lumped in with the A4 range as a whole.

The B9 range covers different trims and model years, so we’ve organised the parts clearly to help you find what suits your car. Check the fitment on each product, and if you’re not sure, the Awesome GTI team can point you in the right direction.

Audi A4 B9 Mods: Bodystyling and Handling

If styling is first on the list, you can build up the look piece by piece. The ECS Tuning Flat Side Skirts give the lower sides of the car a cleaner, sharper finish, while the ECS Tuning Carbon Front Lower Spoiler adds more aggression to the front end.

There’s plenty of scope to build your own Audi A4 B9 body kit using individual styling parts from the range. If you’re after Audi A4 B9 side skirts, check the fitment against your trim and model year, as some options are made for specific versions of the car.

Getting the ride height right can change the whole stance of a B9. The H&R Height Adjustable Spring Kit lets you bring the car down while retaining the factory electronic dampers on compatible models.

Brakes are easy to forget until you start driving the car harder. The EBC Bluestuff NDX Front Brake Pads give you another option if you want a more performance-focused front pad setup.

Why A4 B9 Owners Choose Awesome GTI

Awesome GTI has been working with VW, Audi, SEAT and Skoda cars since 1989, so the different engines and trim levels across the B9 range are familiar ground for us. If you’re planning Audi A4 B9 upgrades, we can help you work out what fits your car and what makes sense for the setup you’ve already got.

If you want more from the engine, you can also book an Audi A4 B9 remap right here. Our team can talk you through the options for your car and carry out the work at our Manchester workshop.

If you’re not sure where to start, contact the Awesome GTI team and tell us what you want from the car. We can help narrow down the parts that suit your B9 before you start buying.

Frequently asked questions

What are the most popular Audi A4 B9 mods?

A lot depends on what you want to change first. Styling parts are a popular place to start, while lowering springs can make a noticeable difference to the way the B9 sits. If performance is higher up the list, an ECU remap is another option for compatible engines.

Do body kit and styling mods affect the Audi A4 B9's warranty?

They can affect warranty cover in some circumstances. Audi states that its warranty doesn't cover damage or defects caused by unauthorised parts or modifications, and additional bodywork itself isn't covered by the manufacturer warranty. If your B9 is still under warranty, check the terms before fitting aftermarket styling parts.

Are Audi A4 B9 mods available for both the Saloon and Avant?

Yes, there are Audi A4 B9 mods available for both body styles, but fitment isn't always interchangeable. Some parts are made for a particular trim or version of the B9, so check the individual product listing before ordering. If you're unsure, the Awesome GTI team can help confirm what fits your car.

Can I fit Audi A4 B9 mods myself or do I need a garage?

That comes down to the part and how confident you are working on the car. Some styling pieces may be manageable at home with the right tools, while suspension work is a more involved job. A remap needs the appropriate software and equipment, so that's something Awesome GTI can handle for you at our Manchester workshop.
