Weber 7636 Porcelain-Enameled Flavorizer Bars are engineered replacements designed specifically for Spirit 300 Series Gas Grills. These heat deflectors measure 15.3 x 2.6 x 2.5 inches and feature a durable porcelain-enameled coating that resists rust and extends longevity. The bars distribute heat evenly across the cooking surface while vaporizing drippings to create authentic smoky flavor and prevent flare-ups. Their robust construction withstands high temperatures and repeated use, making them essential maintenance components for optimal grill performance. Compatible with standard Spirit 300 configurations, these replacement bars restore your grill's cooking efficiency and flavor-infusion capabilities.
