The Arlen Ness 18-446 "Big Sucker" air filter kit is a popular aftermarket option for Harley-Davidson Touring models with airbox intake systems. This kit is designed to provide improved airflow and increased performance by replacing the stock air filter element with a larger, high-flow design. Here are some potential pros and cons to consider before making a purchase.

1. Enhanced engine performance: The larger filter element allows for more airflow into the engine, potentially resulting in increased horsepower and torque. This can lead to improved acceleration and overall riding experience.

2. Easy installation: The kit comes with detailed instructions and all necessary hardware for installation. The filter can usually be installed in under an hour, making it a relatively simple modification.

3. Improved filtration: The high-flow filter element still provides effective filtration, helping to keep the engine clean and free of debris.

4. Custom look: The "Big Sucker" air filter housing adds a unique and distinctive look to the motorcycle, making it a popular choice among Harley-Davidson enthusiasts.

1. Cost: The Arlen Ness 18-446 kit is more expensive than the stock air filter element. The increased cost may not be justifiable for some riders, depending on their budget and desired performance gains.

2. Maintenance: The larger filter element requires more frequent cleaning or replacement compared to the stock filter. This additional maintenance may not be desirable for some riders.

3. Potential noise increase: The increased airflow may result in a slightly louder engine sound, which some riders may find unpleasant.

The Arlen Ness 18-446 "Big Sucker" air filter kit can provide noticeable performance gains for Harley-Davidson Touring models with airbox intake systems. However, the increased cost, maintenance requirements, and potential noise increase may not be desirable for all riders. Ultimately, the decision to purchase this kit depends on individual riding preferences and priorities.

If you are looking for improved engine performance and don't mind the added maintenance and potential noise increase, the Arlen Ness 18-446 "Big Sucker" air filter kit could be a worthwhile investment. However, if you prioritize a quieter riding experience or have a limited budget, you may want to consider other options or wait until you can afford the upgrade.
