Review K N FILTERS New Air Filter For Model's P#s fits BUELL

Introducing the BU-1108 Air Filter, specifically designed for Harley-Davidson Buell 1125R motorcycles with the engine numbers 1011-1725. This high-performance air filter is an essential upgrade for riders who demand superior engine protection and enhanced filtration.

Crafted from premium cotton media, this air filter boasts exceptional filtering capabilities, trapping even the smallest of particles while allowing maximum airflow for optimal engine performance. The media is pleated, ensuring a large filtering surface area to capture contaminants effectively.

The BU-1108 Air Filter features an oiled design, which not only provides an attractive appearance but also helps in sealing the filter elements for a snug fit in the airbox. The filter comes pre-oiled, but it is recommended to re-oil it before installation and after every few oil changes for best results.

This air filter is a direct replacement for the stock filter, ensuring a hassle-free installation process. The filter housing does not need to be modified for this upgrade. Additionally, the BU-1108 Air Filter is washable and reusable, making it a cost-effective solution for maintaining clean air intake for your Buell 1125R.

By upgrading to the BU-1108 Air Filter, you'll not only improve the overall performance and longevity of your motorcycle's engine but also protect it from damaging particles and contaminants commonly found in the riding environment. This air filter is an investment in the long-term health and reliability of your Buell 1125R.

The Buell 1125R is a high-performance motorcycle that requires proper maintenance, including the use of an appropriate air filter. The BU-1108 air filter produced by K&N is a popular aftermarket option for this motorcycle model. Here are some pros and cons of buying this air filter:

1. Enhanced Air Flow: The BU-1108 air filter is designed to provide better air flow compared to the stock filter. This results in improved engine performance and increased horsepower.

2. Longer Filter Life: This air filter has a longer service interval than the stock filter, which means less frequent filter replacements.

3. Better Filtration: The K&N air filter offers better filtration than the stock filter. It can trap more dirt and debris, ensuring cleaner air enters the engine.

4. Easy Installation: The installation process of the BU-1108 air filter is straightforward and can be completed without any major modifications to the motorcycle.

1. Initial Cost: The K&N air filter may have a higher initial cost compared to the stock filter.

2. Maintenance: While the filter has a longer service interval, it still requires occasional cleaning or replacement.

3. Noise Level: Some users have reported an increase in noise level after installing the K&N air filter.

In conclusion, the BU-1108 air filter produced by K&N offers several advantages, including enhanced air flow, longer filter life, and better filtration. However, it may have a higher initial cost and require occasional maintenance. Additionally, some users have reported an increase in noise level.

Based on the pros and cons, I would recommend the BU-1108 air filter for those who prioritize improved engine performance, longer filter life, and better filtration over a quieter ride and lower initial cost. If noise level is a significant concern, it may be worth considering other air filter options or taking steps to address the noise level, such as using a noise suppressor or exhaust modifier.
