PRODUCT:
Valve Cover Block-off Kit

APPLICATION(S):
Kawasaki Ultra 250X, Ultra LX, STX-15F, STX-12F

PART#:
RK19090-VCB

PRODUCT DESCRIPTION:
Our Valve Cover Block-off Kit is designed to seal off the ports on the valve cover when removing the emission control system for racing applications. There are two major benefits to removing the factory emissions system:

1) For racing applications it is recommended to remove all necessary equipment from your craft for increased reliability and reduced maintenance. This also cleans up plumbing in the engine compartment providing a clean look.
2) To accurately monitor air/fuel ration for tuning purposes you must remove the emissions system. The OEM system pumps fresh air into the exhaust stream throwing off air/fuel ratio.

Plates are precision machined from billet aluminum and anodized to prevent corrosion. Includes two block-off plates and installation instructions.

They help the engine maintain a consistent and more accurate A/F ratio. This is important for competition and precise tuning. Plus they clean up the look of the engine. Installing them won't hurt the engine or it's performance.
