K&N® Offers Performance Air Intake Systems for Harley-Davidson Motorcycles
- 1 Dec 2
| For motorcyclists dedicated to the iconic Harley-Davidson brand—and interested in a guaranteed increase in horsepower and torque—K&N® offers performance-enhancing air intake systems available in multiple styles and finishes for H-D motorcycles, now available and 50-state legal for hundreds of additional models. Protect your engine from most harmful dust, dirt, and contaminants, and reap benefits including a guaranteed increase in horsepower and torque, top-quality engine protection, and robust engine sounds on acceleration.
[Please note that using a K&N replacement air intake system will not void your factory warranty; in the U.S., manufacturers must provide evidence that an aftermarket part is the cause of a necessary repair in order to void or deny warranty coverage. The Consumer Products Warranty Act of 1975 (also known as the Magnuson-Moss Warranty Act) protects consumers’ rights to their warranty coverage.]
RK SERIES INTAKE SYSTEMSRK Series Intake Systems feature an oversized K&N® High-Flow™ Air Filter, dyno-tuned velocity stack, and integrated breather system—helping to provide a significant increase in airflow and engine performance. RK intake systems fit neatly behind the factory air cleaner cover to maintain a stock appearance, and come in either a standard capacity or large capacity style depending on your performance needs.

I would definitely recommend this intake to anyone who seriously wants to feel instant power.” [Product #: RK-3933XB] Part numbers for various H-D models are listed below (all 50-state legal).

Mercedes-Benz produced its first V8 engine in 1963, and remained in production until 1981. Setting the stage for future Mercedes V8s, the M100 was fairly sophisticated for the day. It featured an iron block with aluminum cylinder heads, a single overhead camshaft driving two valves per cylinder (exhaust valves were sodium filled) forged pistons, connecting rods, and crankshaft, and dry sump engine lubrication.
The V8 Mercedes-Benz engine that's the subject of this article is the M273 engine, which while it's been installed in a variety of different Mercedes models all take the same 33-2181 K&N replacement air filter. An evolution of the M113 engine, the M273 features an aluminum block and cylinder heads, forged steel connecting rods. The hypereutectic aluminum block is linerless, utilizing silicon in the bores to reduce piston scuffing. A dual-length Variable Length Intake Manifold and SFI fuel injection provide induction. New features carried over from the M272 include DOHC aluminum cylinder heads, 4 valves per cylinder, and Continuous VVT. The system is capable of adjusting each camshaft separately, through a range of 40 degrees. A new electronically controlled cooling system optimizes control of engine temperature. Mercedes-Benz installed this same filter on a wide range of vehicles, starting in 1998 and covering models as diverse as the G Class, S Class, R Class, SL and SLK Class, GL and GLK Class and the C Class. Regardless of whether your Mercedes-Benz is powered by a V6 or V8 engine, installing a K&N filter provides an increase incremental air flow to the engine up to 50%. And by increasing the flow of air, you can expect better throttle response and improved torque across your Mercedes engine's operating range. K&N air filters are manufactured from multiple layers of oiled cotton filter media, which accounts for their long service life. The major benefit is that oiled cotton allows for both increased air flow and excellent filtration. Many less-expensive filters are made from more restrictive paper media that can easily clog and actually limit the output potential of the engine. K&N verifies the performance of each filter design through the company's in-house efficiency testing, in compliance with ISO 5011 standards. This rigorous testing confirms that K&N filters provide a high volume of intake airflow without sacrificing engine longevity. You can order the filter simply by clicking on the part number 33-2181 and while you're at it, grab a Air Filter Cleaning Kit, part number 99-5050. You can view all the K&N performance products for any vehicle by using the Search by Vehicle tool and you can find a local K&N retailer by plugging your location into the K&N Dealer Search as well. The K&N 33-2181 air filter fits the following Mercedes Benz models: |
