Flavorizer Bars for Weber Spirit II & Spirit 300 Series - Stainless

In this review the PETKAO Flavorizer Bars are examined as a direct replacement for Weber Spirit and Spirit II 300 Series grills from 2013 to current model years. The bottom line: these 304 stainless steel flame guards are aimed at owners who want a closer match to original GS4 performance with improved ventilation and even heating. Installation is straightforward and the five-pack covers a full 3-burner grill, making these bars the most practical choice for anyone replacing warped or corroded flavorizer bars.

Key Features

• Compatibility: Fits Spirit and Spirit II 300 Series grills including E-310, E-320, E-330, S-310 and related LX models, so buyers can be confident of a correct fit for up-front control models.
• Material: Made from high-quality 304 stainless steel, which resists rust better than painted steel and keeps bars structurally sound under regular heat cycles.
• Complete set: Packaged as a five-pack, the set replaces all flavorizer bars on typical three-burner Spirit GS4 grills so you can swap the full set at once.
• Ventilated design: Each bar has four notches (two cutouts per side) to improve ventilation for more even heating and better grease vaporization.
• Dimensions and gauge: Each bar measures about 15.3 in x 2.6 in x 2.5 in and is 16GA thickness, offering a balance of durability and weight for stable placement above the burners.

Who It's For

This replacement set is best for owners of Weber Spirit and Spirit II 300 Series grills who need an exact-match repair part that maintains GS4-style performance. It suits people replacing heavily corroded or warped factory bars and those who prefer stainless for longevity and easier cleaning.

It is less appropriate for owners of non-Spirit models or very old Spirit grills without up-front controls, and for buyers who want cast or ceramic heat retention parts rather than stainless flame guards.

Pros & Cons

Pros

• Solid stainless construction gives a cleaner look and better corrosion resistance than stock painted bars.
• Four-notch ventilated pattern promotes even heat and easier observation of burner flames when lighting.
• Good fit and function for Spirit II GS4 three-burner grills, simplifying replacement.

Cons

• Longevity reports are mixed; some users find durability excellent while others note wear over time, so life expectancy may vary with use and maintenance.
