Featured Products




Comments: Designed for circle track applications, this kit provides additional horsepower by sealing the bottom base underneath the hood forcing the cooler, outside air into the carburetor instead of the air under the hood. The kit includes a bottom base, air cleaner top and a 1” sure seal. The height of the sure seal can be adjusted to insure a tight seal to the base of the hood. (Does not include air cleaner.)
