Introducing the Engineering SU-4002 Air Filter, a high-performance replacement option for ATV and UTV riders who demand superior engine protection and enhanced filtration capabilities. Designed to fit select Kawasaki KFX400 models from 2003 to 2006 and Suzuki LT-Z400 models from 2003 to 2009, this air filter is engineered to outperform the original equipment and extend the life of your engine.

The Engineering SU-4002 Air Filter boasts a pleated cotton design that provides a larger filtering surface area compared to traditional paper filters.

The SU-4002 air filter is a popular aftermarket option for the Kawasaki KFX400 (2003-2006) and Suzuki LT-Z400 (2003-2009). Here are some pros and cons to help you make an informed decision about purchasing this air filter:

1. Enhanced engine performance: The SU-4002 air filter provides better engine performance by allowing more air to flow into the engine. This results in increased horsepower and torque.

2. Improved filtration: The air filter uses a pleated design and high-quality filter media to capture more dirt and debris, ensuring cleaner air enters the engine.

3. Durability: The SU-4002 air filter is made of high-density foam and is designed to last longer than the stock air filter.

4. Easy installation: The air filter can be installed easily without any modifications to the engine or airbox.

5. Better fuel economy: By allowing more air to flow into the engine, the SU-4002 air filter can help improve fuel economy by reducing the amount of fuel needed to generate the same amount of power.

1. Cost: The SU-4002 air filter is more expensive than the stock air filter. While the performance benefits may be worth the cost for some riders, others may prefer to save money and stick with the stock filter.

2. Maintenance: The SU-4002 air filter requires more frequent cleaning or replacement than the stock air filter. This is due to the increased airflow and the finer filter media.

3. Noise level: Some riders have reported that the SU-4002 air filter produces more noise than the stock air filter, although this may be subjective and dependent on individual riding styles.

The SU-4002 air filter offers several benefits over the stock air filter, including enhanced engine performance, improved filtration, durability, and potentially better fuel economy. However, it also comes with some drawbacks, such as a higher cost, more frequent maintenance, and potentially increased noise level. Ultimately, the decision to purchase the SU-4002 air filter depends on your riding style, budget, and preferences. If you prioritize performance and are willing to invest in regular maintenance, the SU-4002 air filter may be a worthwhile investment. Otherwise, the stock air filter may be a more cost-effective and low-maintenance option.
