Fits 3-Series G20, 4-Series G22
Part No: 33-3072 Quantity Required: 2 (Filters are sold individually)
Let’s be honest, you own one of the most advanced and powerful V8s on the market. The 4.0-litre Bi-Turbo engine in your AMG is a masterpiece of “hot-vee” engineering, but its twin turbos are still inhaling through restrictive, disposable paper filters.
It’s time to let your engine breathe. The K&N High-Flow Panel Filters are the single most effective “first mod” you can make. They are engineered to be the last air filters you will ever buy for your car.
Designed as a direct drop-in replacement for the factory paper filters, this is the simplest and most cost-effective way to improve your engine’s performance. K&N’s state-of-the-art, oiled cotton gauze material provides up to 50% more airflow than a standard filter. This allows your M177 engine to breathe deeper, resulting in increased horsepower, sharper throttle response, and a more pronounced and aggressive induction sound from the twin turbos.
Best of all, these filters are fully washable and reusable. Instead of throwing away your filters at every service, you simply clean and re-oil your K&Ns, making them good for another 50,000 miles. They are built to last a lifetime and are backed by K&N’s famous Million-Mile Limited Warranty.
Key Features & Benefits:
MSL Recommends: Your 4.0L V8 AMG has two airboxes (one on each side of the engine) and requires two (2) of these filters. Please ensure you add two to your basket to complete the set!
This filter (33-3072) is designed for a wide range of Mercedes-Benz and AMG models equipped with the 4.0L M177 & M176 Bi-Turbo V8 engine.
