RS4

Audi RS4 performance parts cover four very different cars under one badge, running from the original 2.7-litre biturbo V6 in the B5 through to the 2.9-litre twin-turbo V6 in the current B9. Awesome GTI stocks RS4 aftermarket parts split by generation, so you're shopping for your exact car rather than a generic RS4 in name only.

Every RS4 Generation, Covered

Whether you're running the B5's 2.7 biturbo V6, the naturally aspirated 4.2 V8 shared by the B7 and B8, or the 2.9 twin-turbo V6 in the B9, parts are split by generation so fitment isn't guesswork. Browse the B5,  B7, B8 and  B9 ranges directly, each stocked with suspension and exhaust upgrades built around that specific engine and chassis.

What Sets Our RS4 Performance Parts Apart

Frequently asked questions

Is the RS4 faster than the RS3?

No, the smaller RS3 is quicker in a straight line despite having less power. The current RS4 Avant runs 0-62mph in around 4.1 seconds, while the RS3 manages it in about 3.6 seconds thanks to its lighter body.

What's faster, the RS4 or BMW M3?

The BMW M3 Competition is quicker from the factory, reaching 0-60mph in around 3.4 to 3.8 seconds against roughly 4.1 seconds for the RS4. The M3's extra power makes the difference, though the RS4's quattro system adds grip the M3 can't match in standard form.

What is the best Audi RS4 ever made?

There's no official answer, but the B7 is the generation most enthusiasts point to, thanks to its naturally aspirated V8 and the way it drives. The original B5 remains a close second for many, as the car that started the RS4 story.

What are the most popular performance upgrades for the Audi RS4?

Remapping is one of the most popular upgrades across every RS4 generation, since the turbocharged and biturbo engines respond well to software changes. Exhaust upgrades and coilover kits are common next steps, sharpening sound and handling.
