For Yamaha Raptor 700 & Kawasaki KFX models. Our 8ply filters offer maximum protection.

Testing to the Highest Standard

The ISO (International Organization for Standardization) establishes and specifies uniform test procedures, conditions, equipment and a performance report to permit direct laboratory performance comparison of air filters and induction systems.

Testing to these high standards enables us to accurately measure our products against not only OEM [Original Equipment Manufacturer] equipment, but also to the competition, allowing us to establish the air filter performance benchmark, which we are determined to do.

ISO is a worldwide federation of national standards bodies. The work of preparing International Standards is normally carried out through ISO technical committees. The specific individual International Standard utilized by FCI and automotive manufacturers establishes and specifies uniform test procedures, conditions, equipment, and a performance report to permit the direct laboratory performance comparison of air cleaners, in this case, those used on internal combustion engines and compressors used in automotive and industrial applications.

The performance characteristicsof greatest interest are airflow restriction (differential pressure), dust collection efficiency and dust capacity. The ISO 5011 Standard is what FCI adheres to as we seek innovations and improvements in our product line, and to test our products so they meet the highest standard possible. We feel this is the standard that all performance filter manufacturers should be using to develop their products.

The end result is simple: increased horsepower by reducing the restriction of the air filter and/or intake kit while still protecting the engine. Trust your performance needs to the only performance filter tested to these standards and post results – Trust that we only sell the best!
