YFZ450 Fuel Customs Replacement Filter (also fits YFZ450R)
Fuel Customs 8ply filters offer maximum protection and tested to the Highest Standard. Proven to be superior to K&N. 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. 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!
