  • 14 inch outside diameter fits K&N air filters: E-3740, E-1650, E-3750, E-3760, E-3770 and other variants
The K&N 14 inch air filter top and base plates fit any round 14 inch K&N high-flow air filter for boosting the performance in carbureted race cars, hot rods, muscle cars and pickup trucks. The plates are made from lightweight aluminum with a spun aluminum finish featuring K&N logos embossed on the outer edge of the top plate. The base plate fits carburetors with a 5-1/8 inch air horn flange and drops the filter 1-1/2 inches below the carb flange. The drop base design helps to maximize air filter height while still clearing the hood in many custom applications. These K&N 14” top and base plates will work with various heights of K&N high-flow air filters such as the 2-5/16 inch tall air filter E-3740, 3 inch tall air filter E-1650, 4 inch tall air filter E-3750, 5 inch tall air filter E-3760, 6 inch tall air filter E-3770 and several other variations meant for drag racing or off-road racing use.
