TR6 Stainless Steel Carburetor Heat Shield for the stock Z-S Carbs Designed to fit HS6 Conversions, too!This will improve fuel handling(performance!) and avoid fuel percolation in extreme heat conditions.Removal of the carburetors is unnecessary. Remove your air filter(s), add two new carb gaskets, and replace with existing hardware. The Shield deflects heat from the fuel bowls and covers the fuel line at the carburetors. These were process engineered and manufactured on production tooling.
