APR ECU Upgrade S4 B6/B7 4.2 V8

The ultimate chip upgrade for the S4 4.2 engine is available from APR. After months of long nights and many hours of dyno work we are pleased to offer you chip tuning that is second to none. We have worked hand in hand with many customers to deliver a chip that works. Expect increases in throttle response and a smoother, more powerful top end.


APR Snub Mount 1.8T/2.7T/2.0

APR’s Snub Mount Upgrade replaces the front engine mount on the car. This mount enhances upshifting and downshifting, reduces driveline shock, and helps power transfer by taking up excess drivetrain slack.



APR’s B6 & B7 S4 Exhaust is offered as both a full or as a catback system. The catback system is a complete stainless steel, mandrel bent, cat-back exhaust. The exhaust is a dual 2.25″ system that begins at the factory downpipes and continues to an innovative centre muffler. The exhaust then splits and each mandrel bent pipes goes to its own muffler with a 3.5″ (90mm) bevel-cut, round tip.


Panel filter for a direct replacement of factory element. We can also supply and install Cold Air Intake systems. Please call for a quote.
