Arlen Ness Air Filter for Method Clear Model 18-090 Replacement

Description

Product Overview

The Arlen Ness air filter (model 18‑090) is engineered as a direct replacement for the Method Clear air intake system, offering a high‑flow design that maximizes engine breathing while maintaining superior filtration standards. Constructed from a durable, high‑quality cellulose blend, the filter media captures dust, pollen, and microscopic particles without restricting airflow, which translates to smoother throttle response and improved fuel efficiency. The filter’s dimensions of 6.5 x 6.5 x 2.5 inches ensure a precise fit within the existing housing, eliminating the need for modifications or additional hardware. Each unit weighs only 7.7 ounces, making it lightweight yet robust enough to withstand the rigors of both street riding and off‑road adventures.

The design incorporates a sealed rubber gasket that creates a secure, leak‑free seal when installed, preventing unfiltered air from entering the engine. The filter’s high‑flow construction reduces intake restriction, which can enhance horsepower by up to 5 percent in some applications, according to independent testing. Additionally, the filter is reusable; a simple cleaning and re‑oil process restores its performance, extending the service life far beyond disposable alternatives. This sustainability aspect aligns with the growing demand for environmentally responsible aftermarket parts.

Independent flow testing conducted by third‑party laboratories confirms that the Arlen Ness filter delivers up to 12 percent greater volumetric airflow compared to the OEM filter, while maintaining a filtration efficiency of 99.5 percent for particles down to 5 microns. This balance of performance and protection is critical for high‑revving engines that demand both power and reliability. The filter’s cellulose media is engineered to retain its structural integrity under high temperature conditions, ensuring consistent performance even after prolonged exposure to engine heat.

The environmentally conscious rider will appreciate the filter’s reusable nature, which eliminates the need for frequent disposables. By cleaning and re‑oiling the filter, users reduce landfill waste and lower the carbon footprint associated with manufacturing new filters. Arlen Ness also partners with recycling programs to responsibly dispose of used cleaning solvents, reinforcing a commitment to sustainable practices throughout the product lifecycle.

Usage

Ideal for motorcycles equipped with the Method Clear air intake, this filter excels in a variety of riding conditions, from daily commuting to high‑performance track days. Riders who demand quick acceleration and consistent power delivery will notice the immediate benefit of reduced intake turbulence, especially during rapid throttle changes. The filter also performs admirably in dusty environments such as desert trails or gravel roads, where its robust media traps contaminants while allowing sufficient airflow to keep the engine cool.

Installation is straightforward: remove the stock filter, place the Arlen Ness unit into the housing, and secure it with the existing bolts. No additional tools or modifications are required, making it an excellent choice for both seasoned mechanics and DIY enthusiasts. After installation, the filter can be inspected visually for proper seating, and a quick test ride will confirm the enhanced response. For riders who prefer regular maintenance, the filter can be cleaned with a dedicated air filter cleaner, lightly re‑oiled, and reinstalled, ensuring peak performance throughout its lifespan.

For long-distance touring, the filter’s ability to maintain optimal airflow reduces engine strain during extended highway cruising, contributing to smoother power delivery and lower fuel consumption. Riders who frequently travel across varied terrains will benefit from the filter’s capacity to adapt to changing air quality, providing consistent protection whether riding through urban smog or remote mountain passes.

Maintenance is simplified by the filter’s modular design. The housing can be accessed without removing other components, allowing quick inspection during routine service intervals. The cleaning process requires only a spray of approved cleaner, a gentle wipe, and a thin layer of oil, which can be completed in under ten minutes. This efficiency encourages regular upkeep, preserving engine health and extending the filter’s usable life.

FAQ

Can this filter be used on other motorcycle models?

The filter is specifically sized for the Method Clear air intake system. While it may physically fit some similar housings, we recommend using it only on compatible models to ensure proper sealing and performance. Installing it on an unsupported model could lead to air leaks, reduced filtration efficiency, or potential engine damage. If you are unsure whether your bike is compatible, consult the product manual or contact our support team with your motorcycle’s make and year for confirmation.

How often should I clean and re‑oil the filter?

For most riders, cleaning the filter every 5,000 to 7,500 miles provides optimal airflow and filtration. In dusty or off‑road conditions, more frequent maintenance—such as every 3,000 miles—may be beneficial. The cleaning process involves spraying a dedicated air filter cleaner, allowing it to dry, applying a light coat of filter oil, and reinstalling the filter. Follow the step‑by‑step guide included with the product to avoid over‑oiling, which can affect performance. Regular maintenance not only preserves engine health but also extends the service life of the filter.

Will installing this filter affect my motorcycle’s warranty?

Arlen Ness products are designed to meet or exceed OEM standards, and installing this filter does not void the manufacturer’s warranty. However, it is always advisable to review your bike’s warranty terms for any specific clauses regarding aftermarket parts. If a warranty claim arises, providing documentation of proper installation and maintenance can help ensure a smooth process. Our support team can also assist in communicating with the manufacturer if needed.

What tools are required for installation?

Installation requires only basic hand tools such as a socket wrench or screwdriver to remove the stock filter and secure the new unit. No specialized equipment, drilling, or modifications are necessary. The filter’s design includes pre‑drilled bolt holes that align with the existing mounting points, allowing a bolt‑on fit in minutes. If you are unfamiliar with basic motorcycle maintenance, the included step‑by‑step guide and online video tutorial will walk you through the process safely.
