Project B8 S4 3.0TFSI



A long time customer of BFI recently had the fortune of upgrading from his B6 S4 to a brand new B8 3.0TFSI S4 sedan. While the B6 was an impressive car - with it's thundering 8 cylinder bellow, we can't help but be swayed by the overall refinement of the newer B8 platform. The chassis and interior are everything that one has come to expect from a modern Audi with the return to untapped performance potential laying inside that 6 cylinder supercharged power plant. It took little convincing to persuade our friend to pull the trigger on the APR Audi B8 S4/S5 3.0 TFSI ECU Upgrade in fact, he was chomping at the bit to have us perform the minor surgery on his ECU. We feel certain that it was worth the wait as the drivability and performance gains are significant. On paper the numbers the numbers might not seem mind blowing, however the real world results do not lie.

While we had access to the S4 we took the opportunity to use it as a test bed for expanding our wheel spacer line. Unique to the B8 chassis is a 66.6mm wheel centerbore - meaning our previous spacer offerings, while the same 5x112 bolt pattern will not work due the more ubiquitous 57.1mm centerbore that is found with the older vehicles. What we came up with is a custom designed wheel spacer specific to the B8 Chassis. See our entire line of BFI Audi B8 Wheel Spacers here.

While the spacers did a great job of making the factory S4 wheels sit properly, it just wasn't quite enough for this project. The OE rollers ended up being ditched in favor of a set of 20" BBS CH-Rs. And what would an amazing set of wheels be without an improved suspension in the form of Bilstein coilovers. A Magnaflow Catback exhaust was originally installed but eventually removed in favor of an A.W.E system. Other minor modifications include VAG-COM tweaks and ultra dark tint. To round out this project we look forward to installing the recently released APR 3.0 TFSI Supercharger Pulley Upgrade in an attempt to squeeze every ounce of performance out of the S4. Check back in the very near future for updates and results.
