Audi S4 (B7) Performance Parts, Mods, and Upgrades
The Audi S4 B7 is widely regarded as the definitive expression of the naturally aspirated V8 S4. Produced from 2005 to 2008, the B7 carried forward the 4.2L V8 that debuted in the B6 but delivered it through a meaningfully evolved chassis — lighter in construction, sharper in geometry, and more composed at the limit than its predecessor. It is also the generation that gave rise to the RS4 B7, one of the most celebrated performance cars Audi has ever produced, and that proximity to a genuine motorsport benchmark sets the context for everything the B7 S4 aspires to. At IND Distribution, our S4 B7 collection approaches this platform with the seriousness it deserves, focusing on components that advance the V8's performance within the framework of the B7's more refined dynamic character.
The Supersprint exhaust components in our B7 catalog address the heart of the V8's flow architecture. The Supersprint A4 B6/B7 Quattro Centre Exhaust replaces the restrictive factory mid-section, unlocking the pressure differential that constrains the V8's exhaust pulse at moderate to high engine speeds. The Supersprint Connecting Pipes Kit completes the picture, providing precision-engineered bridging hardware that ensures the full system operates with structural integrity and symmetrical flow across both exhaust banks. Together these two components form an upgrade path that improves mid-range response and allows the 4.2L to breathe more freely through the rev range without altering the factory tail section or requiring a full exhaust rebuild.
The CANchecked instrumentation suite brings the B7's operational data into the modern era in a way that the factory simply never provided. The SWD32 Multi-Function Display, SLM08 Shiftlight Module, and FLP01 oil and fuel pressure sensor deliver real-time monitoring across the parameters most relevant to a high-revving V8 under sustained performance use. The TCC04 Thermocouple CAN Converter adds exhaust gas temperature tracking to the data set, giving the driver the thermal visibility that matters most when the 4.2L is at the top of its operating envelope. The full range of VAG-compatible diagnosis and connection cables ensures the entire CANchecked ecosystem integrates cleanly with the B7's electrical architecture.
The Acexxon Universal and Heavy Duty Front Lip Protectors complete our B7 offering, providing dependable protection for the front splitter against the road debris that accompanies driving the S4 as it was intended. At IND Distribution, we bring the same commitment to product quality and platform knowledge to the B7 S4 that we apply across our entire European catalog. The B7 is a platform with genuine pedigree and it rewards investment in the right components. Our job is to make sure every part we supply is one of them.
