14in. Air Cleaner Baseplate

The K&N Engineering 14in. Air Cleaner Baseplate (model 85-3549) is a precision-engineered component designed for high-performance intake systems. This baseplate serves as a critical interface between your air filter assembly and the engine's intake manifold, making it essential for those upgrading to K&N's filtration solutions. It is suitable for various applications, including custom intake systems and high-performance builds.

Manufactured to K&N's exacting tolerances, the 14-inch baseplate features a robust design that maintains consistent seal pressure across the filter-to-intake interface. This prevents unmetered air leaks that can degrade performance and engine efficiency. The baseplate's precision geometry ensures proper filter element seating and supports K&N's reusable cotton-gauze media without flexing or deformation under intake vacuum.

Ideal for mechanics and enthusiasts standardizing on K&N intake systems, this baseplate integrates seamlessly into tight engine bays while providing the structural rigidity necessary for reliable long-term operation. Its engineered construction accommodates custom ducting and velocity stack modifications without compromising seal integrity, making it a versatile choice for various performance applications.
