Philosophy / Technology
Engine tuning and performance upgrades have a long tradition at AC Schnitzer. To be on the safe side, we forgo achieving the possible maximum power in favour of greater durability. Many of our performance upgrades are therefore designed to increase torque rather than horsepower. After all, torque is what you feel when, for example, you are "pressed into your seats" when moving off. Petrol The performance upgrade consists of a control unit for retrofitting in the vehicle. The control unit ensures that the data is processed depending on the engine speed and accelerator pedal position, and that the values ??for boost pressure, rail pressure and air mass are passed on to the standard engine control unit. The parameters are slightly increased by the AC Schnitzer performance upgrade. This achieves a model-dependent power increase of up to 20% of the engine and increases engine efficiency. During development, we check in which engine speed range the greatest increase in torque is achieved. Subsequently, the modified parameters are reduced in a controlled manner for the high-rev range above 5000 rpm. This prevents the engine from overheating during longer, fast journeys. The standard engine protection parameters are retained with the AC Schnitzer performance upgrade. In addition, the AC Schnitzer performance upgrade also features extensive additional parameters to protect the engine and drivetrain, such as cold start and overheat control.

Cold start control
The AC Schnitzer performance upgrades are only activated from approx. 1000 rpm and an oil temperature of 80°C.

Overload / overheating control
The power is automatically reduced to the standard power when the water temperature reaches 115°C.

Extensively tested
AC Schnitzer performance upgrades undergo extensive testing on racetracks, test benches, and in everyday road traffic. These tests last up to nine months and cover several tens of thousands of kilometres.

Performance upgrade installed - what about the warranty?
For all AC Schnitzer performance upgrades, AC Schnitzer provides a country-dependent warranty of up to 5 years from the date of first registration, with a mileage of up to 120,000 km, on the components moved by the engine. For M models, AC Schnitzer provides this country-dependent warranty of up to 4 years from the date of first registration and up to 80,000 km. This gives you peace of mind in the event of a problem. You can find our complete warranty conditions here.

Appraise
The parts certificate is an official document that permits the use of tuning parts on public roads under the StVZO (Road Traffic Licensing Regulations) in Germany (and several other countries). After the part described in the certificate has been installed or modified, the vehicle must be presented to an official inspection centre. The inspector will verify the correct installation and authenticity of the part and then enter the modification in the vehicle documents. The vehicle's official operating license thus remains valid. The parts certificate is part of the delivery package.

Adjustable Support for Side Sleeping
Size: Body(Pack of 1), Color: White
The pillow is long and full, filled with shredded memory foam, and the cover feels smooth with a sturdy zipper. When I adjusted the fill, the foam shifted easily and settled without clumping, which made it simple to fine-tune the firmness. I ordered this pillow for extra joint support. In use, it stayed in place overnight and kept my hips and shoulders better aligned, especially when sleeping on my side. Memory foam naturally contours to pressure, which helps with joint support, but it can also hold a bit of warmth after several hours. The washable cover came off cleanly and went back on without stretching. It performed consistently and felt comfortable for daily sleep, and the adjustable fill and stable support explain the positive overall evaluation. This is a long pillow and takes up a lot of space, but it's comfortable and durable and easy to use. (Review is for HOMELAB Adjustable Shredded Memory Foam Body Pillow, 20x54 Long Pillow for Back)

Worth every penny
Size: Body Pillow & Pillowcase, Color: White
This thing is awesome. The pillow case is super soft too. You do need to let it unfold and air it out a bit, it’s present but not overwhelming but I think that applies to similar products. I use it when I lounge in bed. I have a king-size bed. I put it under my knees when I lay down and lay back, propped up a bit to watch movies. It’s perfect.

Better than snuggling a spouse.
Size: Body Pillow & Pillowcase, Color: White
This pillow is, can I say, 'dreamy?' It is so cushy and the cover is like buttery soft velvet. I was afraid it would be lumpy with the shredded foam filling, but it's not at all. It holds its shape and ensures a good nights' sleep. One thing, the box it came in said "Feather and Down," which almost made me send it back unopened, thinking they sent the wrong item. The pillow comes shrink-wrapped into an unbelievably small size, so there's little chance of getting it back in the box once opened. It does puff up to full size in just a matter of a couple minutes. Great purchase.

Too bulky
Size: Body Pillow & Pillowcase, Color: White
It is too big and not easy to squish or manipulate it to squish it into the shape you want it to fit to my body.
