S4 4.2L

Audi S4 B6-B7 Supercharger
The MotoDyne traditional Belt Driven s4 supercharger is our first successful supercharger system for the s4, making 448hp at the crank and 390Ft of Torque. It shares a lot of components of our earlier kits, and has proven itself in the real world since 2004. The one disadvantage to this system is the lengthy installation and disassembly time involved in removal of the b6- b7 s4 nose.

Audi S4 B6-B7 Hydra-Drive Supercharger
The MotoDyne S4 BELTLESS supercharger

(click here for details)

is a concept that MotoDyne holds a patent on, using the manifold only from our first successful s4 supercharger system. We decided to push the design past conventional thinking, and after three years of development and testing, we have now perfected this unique compressor system.

You may wonder why MotoDyne created such a system. The answer is quite simple: This setup eliminates a lengthy installation time because the nose does not have to be removed for fitment.

TCM Transmission Chip Tuning and Soft Coding
Removes the delay between tip shifts, and will allow hold to redline. MotoDyne has tested many Tiptronic powered S4 vehicles with different levels of performance including supercharging and N20.

MotoDyne can custom tune your TCM transmission control module to the desired needs. Combined with our first gear start kit, we can remove almost a full second off quarter mile times without engine modifications.

K&N Panel Filter B6 S4
Replace your factory paper air filter with a lifetime-lasting cloth K&N filter. This makes a very favorable modification for the B6 S4. On cars with the single feed fuel rail setup, this filtration application must be chosen as opposed to a cone filter to prevent excessive overfueling (this car comes from the factory with a rich fuel mixture).
Price: $99.00

Current Quantity in stock: 3


Cold Air Induction Kit
This kit contains a K&N cone filter, a 3 inch charge tube, air pump inlet filter, and heat shield. MotoDyne recommends this application for the B6 fuel system with regulated rail and return line. A gain of 9-10 horsepower will be achieved.

MotoDyne does not recommend this filtration setup on vehicles equipped with a single feedline fuel rail because this will promote overfueling. However, this kit will become favorable if other significant modifications are made to the car.

Driveline Stabilizer Bar
It is a stout piece of hardware with heavy plate steel ends with a beefy center section, that attaches to the tail end of your transmission. This will remove the slop in the driveline normally experienced when creeping along in traffic while in 1st or 2nd gear (Car and Driver called it "rubber banding"). Noticeable when the mass of the car and the torque of 1st gear fight each other. Other benefits are crisper, more positive feeling shifts and a direct transfer of torque to the wheels rather then the rubber mounts when letting out the clutch quickly.
