This is the perfect intake upgrade for the Audi S4 and S5 (B9). It flows 31% more than stock, reduces pressure drop, and improves turbocharger efficiency. This directly translates to +19 AWHP and +20 AWFT-LBS of torque on top of our Stage 1 (93) tune making this a simple upgrade for more power you can feel, and does so at an incredible value.
Our system is a full upgrade as it replaces all of the intake components from the inlet scoop all the way to the turbo inlet. This is extremely important as focusing …

The APR Suspension Control Unit (SCU) Upgrade directly replaces your factory suspension controller with a new unit that enables advanced control over your vehicle’s factory electronic shocks. The factory controller only operates in a “soft” or “stiff” state with no behavior in-between, despite the incredible capability of the factory electronic shocks.
Our controller has advanced programming that takes various inputs to provide fine-tuned control over the shocks in real time. The controller still retains factory comfort and sport functionally, and it doesn’t compromise ride quality for performance. However, both modes rapidly increase performance depending …

APR Iridium Pro Spark Plugs are the excellent upgrade for tuned engines. Our spark plugs are made from Iridium, which is one of the strongest materials you can use in this type of application.
They run cooler, resist preignition, last longer than other materials with higher melting points, and even require less voltage to produce a strong spark. The electrode is harder and stronger than other materials, can dissipate heat more easily, is better protected from melting, cracking, and other limitations found with standard plugs.
These plugs were designed for use on tuned and higher …
