Review MERCEDES benz Supercharger Assembly fits CROSSFIRE SLK32 C32 AMG 2001–2006

The **Mercedes-Benz A1120900080 (2001 2006) SLK 32 AMG Crossfire SRT6 Supercharger** is a rare and highly coveted piece of automotive engineering, embodying the pinnacle of Mercedes-Benz s high-performance roadster lineage with a blend of raw power, cutting-edge technology, and a design that turns heads even by today s standards. Built upon the same mechanical foundation as the SLK 32 AMG but elevated to a whole new level of aggression, this model is the first and only production SLK to feature the legendary **5.4-liter V8 supercharged engine**, a powerplant that was originally developed for the iconic **Mercedes-Benz SLR McLaren** and later adapted for the **CLK 63 AMG**. The **A1120900080** designation marks the chassis code for this exclusive variant, which was produced in limited numbers making it a true collector s item for enthusiasts seeking a blend of track-ready performance and road-going refinement.

Under the hood, the **SRT6 Supercharger** (Supercharged Racing Technology) delivers an astonishing **420 horsepower** and **406 lb-ft of torque**, propelling the SLK from 0-60 mph in just **4.6 seconds** and achieving a top speed of over **160 mph** numbers that were revolutionary for a roadster of its time. The **5.4L M113 V8** is paired with a **6-speed manual transmission** (though an optional **5-speed automatic** was available), and the supercharger, while adding a distinctive growl and a noticeable boost in low-end torque, is carefully tuned to avoid excessive lag, ensuring a linear and engaging driving experience. The engine s aluminum block and cylinder heads, combined with a forged crankshaft and high-flow internals, make it a durable yet exhilarating powerhouse that still commands attention on modern tracks and drag strips.

The **Crossfire** designation refers to the model s aggressive styling cues, which set it apart from the standard SLK 32 AMG. The front of the car features a **bold, split-face grille** with a prominent Mercedes-Benz emblem, flanked by sleek, angular headlights with integrated fog lamps. The **side air intakes** and **vented fender vents** enhance the car s muscular aesthetic, while the **rear spoiler** is a standout feature, offering both aerodynamics and a sporty silhouette. The **18-inch alloy wheels** (available in multiple unique designs) and **low-profile tires** further emphasize the car s performance-oriented nature, while the **blacked-out lower body panels** and **chrome accents** give it a distinctive, high-performance look that feels both aggressive and refined.

Inside, the SLK 32 AMG Crossfire SRT6 retains the **convertible hardtop roof** (which deploys in under 15 seconds) and the **bucket seats with optional leather upholstery**, but the cabin is tuned for performance driving. The **steering wheel** is a sporty, three-spoke design, and the **shift knob** is a polished aluminum piece that adds a touch of luxury. The **instrument cluster** features a **tachometer with a redline at 7,000 RPM**, a clear indication of the engine s high-revving nature, while the **digital display** provides real-time data on boost pressure, oil temperature, and other performance metrics. The **manual transmission** is a highlight, offering precise, engaging shifts that make every gear change feel deliberate and satisfying, though the optional **5-speed automatic** (with a torque converter) provides a smoother alternative for those who prefer convenience without sacrificing performance.

One of the most impressive aspects of the SLK 32 AMG Crossfire SRT6 is its **handling and braking capabilities**, which were state-of-the-art for a roadster in the early 2000s. The car is built on a **shortened chassis** (compared to the standard SLK) with a **lower center of gravity**, contributing to its sharp, responsive cornering. The **multi-link suspension** is tuned for both comfort and sportiness, while the **stiffened subframe** and **reinforced chassis rails** ensure structural integrity under hard driving conditions. The **four-piston Brembo brake calipers** (with **300mm front discs**) provide exceptional stopping power, and the **limited-slip differential** (available as an option) enhances traction in both straight-line acceleration and cornering. The result is a car that feels **light on its feet** yet capable of handling the demands of both daily driving and spirited track sessions.

The **SLK 32 AMG Crossfire SRT6 Supercharger** was never intended to be a mass-produced model only **1,000 units** were manufactured across its production run (2001 2006), making it one of the rarest and most sought-after Mercedes-Benz roadsters ever produced. Its exclusivity, combined with its **unmatched power-to-weight ratio** and **timeless design**, ensures that it remains a highly desirable collector s item today. While the supercharger adds a distinctive growl and a noticeable boost in low-end torque, the engine is also capable of **redlining at 7,000 RPM**, offering a thrilling manual driving experience that few cars can match. Whether cruising along a coastal highway, navigating a twisty backroad, or hitting the track for some high-speed laps, the SLK 32 AMG Crossfire SRT6 Supercharger delivers an unparalleled blend of **speed, agility, and luxury** making it a true legend in the world of performance roadsters.
