Description

The K&N Air Filter KA-4018 is engineered to provide a significant increase in airflow without compromising engine protection. Its design features four to six sheets of cotton gauze sandwiched between two layers of aluminum wire mesh, pleated and oiled to maximize filtration and performance. This construction method, rooted in K&N's motocross racing heritage, allows for dramatically more air into the engine, leading to enhanced horsepower and acceleration. Its high-flow characteristics are specifically created for environments where maximum horsepower and improved acceleration are desired, while still offering robust protection against dirt and dust. Specifications include a height of 1.813 inches (46 mm), and the package contains one air filter. This product is vehicle-specific, and buyers are advised to select their vehicle to ensure proper fitment. K&N filters are known for their performance and longevity in demanding conditions.
