Description
The K&N Filters 85-6852 Air Filter Top and Base Plates are designed specifically for carbureted race cars, featuring oversized 16-inch dimensions. These plates are constructed from lightweight aluminum and come with a spun aluminum finish, showcasing K&N logos embossed on the outer edge of the top plate.
The base plate is designed to fit carburetors with a 7-5/16 inch air horn flange and drops the filter 1-1/2 inches below the carb flange. This drop base design helps to maximize air filter height while still clearing the hood in many custom racing applications. The K&N 85-6852 plates are compatible with a range of 16-inch K&N high-flow air filters, including options such as the 3 inch tall air filter E-3022R and the 4 inch tall air filter E-3026R, among others meant for off-road racing use.
