Audi tuning specialists, APS of Brackley, are offering performance beef-up packages for the current Audi S4 model, taking the 333bhp, 3-litre supercharged V6 up to 410bhp. Torque also climbs, from 344 lb ft to 370 lb ft, while 60mph now comes in just 4.5secs; shaving fours tenths of a second off the factory time.

An S4 with over 400bhp? This Audi is looking for supercar’s toes to tread on.

The Signature tune-ups, which come in Touring and Challenge editions, were developed Stateside by VAG tuners STaSIS, and both packages feature upgrades to the engine ECU (a remap to bring more supercharger boost, fuel and intake air), a freer-flowing exhaust system, and high-performance suspension, brakes, wheels and tyres. 

All of this developed and extensively tested good stuff comes together to sharpen the S4 for fast road use or intensive track day action. 

The STaSIS Signature S4 packages are available now exclusively from APS of Brackley, with prices starting at £12,500 including VAT at 20 per cent and installation. 

Customers are also able to purchase individual Audi S4 STaSIS Signature series components from APS on a piecemeal basis, with prices available on request.
