These flavorizer bars are designed as a direct replacement for Weber Spirit II and I 300 series grills, including models E310, S310, and E315.

Crafted from heavy-duty steel with a porcelain-enameled coating, each bar measures 15.3 inches and is engineered to sit above the burners, channeling heat evenly while capturing drippings. When juices and fats hit the hot bars, they vaporize, creating smoke that imparts a rich, grilled flavor to the food. The set typically includes 15 bars, matching the OEM part numbers 67046, 69797, and 3400302. This configuration ensures a proper fit within the GS4 grilling system found on Spirit II models. Regular use of these bars helps protect the burner tubes from direct exposure to grease and debris, reducing the risk of flare-ups and extending the life of the grill. The porcelain-enameled surface is formulated to resist rust and corrosion over time, even in humid or coastal environments. This coating also makes cleaning easier compared to uncoated steel bars; a simple scrape or burn-off cycle restores their appearance. The underlying steel core provides structural rigidity, preventing warping under high heat. Unlike thin aftermarket alternatives, these bars maintain their shape after repeated heating and cooling cycles. The consistent spacing between bars allows for even heat distribution across the cooking grate, minimizing hot spots. This design promotes uniform searing on steaks, chops, and vegetables, while still allowing small food items to remain stable. Installation is straightforward and requires no special tools. Simply remove the old flavorizer bars, slide the new ones into the designated slots above the burner tubes, and ensure they are seated securely against the back and front of the grill. The bars are lightweight yet durable, making handling easy. Routine inspection every few months ensures that any accumulated grease can be removed before it hardens. For optimal performance, pairing these bars with a regular cleaning schedule helps maintain consistent airflow and heat output. They are also compatible with many Weber Spirit II models sold under the 300 series designation, and they fit both natural gas and liquid propane versions. At a price point of $26.30, this set offers significant value compared to purchasing individual OEM bars. The cost per bar is economical, making regular replacement more accessible. While they are not free or zero-cost, they represent a very affordable solution for maintaining grill performance. Shifting to fresh flavorizer bars can revive the cooking experience on an older grill that has been used for several seasons. The combination of porcelain-enameled protection, precise fit, and straightforward installation makes this set a practical choice for home cooks who want to keep their Weber Spirit performing like new without overspending.
