2000 Audi S4 Twin Turbo. The ultimate B5 S4 Sedan.
Audi RS4 2Bennett

2Bennett has been servicing and modifying this car since 2001 for the original owner.

The beautiful Negaro blue finish was applied in our paint shop and looks fantastic. Custom paint styling shows off the 2B Carbon fiber hood and rear decklid. The roof was also painted black to continue the theme.

The body features a complete RS4 front end including:

= Complete front bumper assembly with Grills

= RS4 Hood grill and headlights

= RS4 Front fenders and rocker extension / covers

The engine performance upgrades began with all of the RS4 bolt on parts such as:

RS4 Aluminum upper air distribution pipe, RS4 Airbox, Airflow meter, fuel injectors, fuel pressure regulator, all RS4 turbo intake pipes and turbochargers, intercoolers, etc.

Also shown are Bailey piston type bypass valves, 2Bennett Silicone intake hoses, APR Aluminum Bipipe

RS4 Turbochargers, RS4 Clutch pressure plate, 2B Aluminum flywheel with 2B Friction disk.

The exhaust manifolds are modified internally by 2B to increased flow dramatically.

Larger exhaust port heads and different camshafts also installed.

The complete complete car with this 2B / RS4 engine package was shipped to APR for time consuming custom software. It makes well over 500 hp on race fuel and still passes California emissions testing on 91 octane. There are 4 programs to choose from for different octanes of fuel. All controlled by Cruise control button with the engine off.

This is still an engine and software package that we sell.

audi s4 crank case oil separator Under the cover where the original Battery lived is the 2Bennett Crankcase oil ventilation / separation system. Not a "catch can". It separates the oil from the air ventilation system allowing it to properly drain back in without destroying the engine when run at such high horsepower. Not having this system is what eats up many of these engines. This system is completely different from catch cans that are sold by most shops.

audi s4 carbon fiber

The tastefully custom painted rear decklid shows off the carbon fiber nicely.

The European rear bumper is slightly shorter and flatter than the American, giving the back of the car of cleaner look.
