QuliMetal Flavorizer Bars for Weber Genesis II/LX 300 — 5‑Piece Porcelain‑Enameled 16‑Gauge Heat Plates

QuliMetal GS4 Genesis II Flavorizer Bars are a set of five porcelain-enameled, 16‑gauge heat plates engineered to replace Weber part numbers 66795/66032 and restore even heat and vaporized flavor to Genesis II/LX 300 grills.

If your Weber Genesis II or LX 300 series grill is showing uneven cooking, exposed burners, or diminished smoky flavor, worn Flavorizer Bars are often the culprit. These QuliMetal replacement bars are sized and finished to slot into Genesis II E-310, S-310, SE-310, E-315, E-325, E-330, SE-330, CE-330, S-335, SE-335, E-335, S-345 and many LX 300 variants from 2017 onward. They protect burners, spread heat more evenly across the cooking surface, and vaporize drippings to reproduce the desirable barbecue aroma.

How will these QuliMetal bars fit my Weber Genesis II 300 grill?

Each heat plate measures 17 1/8" long by 3" wide and 2 1/8" high—dimensions matched to the OEM 66795/66032 parts. The set contains five bars made to the same footprint as the originals so installation is typically straightforward when the grate and old bars are removed.

• Exact length and width tailored to Genesis II/LX 300 series models (2017+).
• Sold as a complete five-piece set for middle, left, and right burner coverage.
• Check your grill model and existing bar size before ordering.

What makes the QuliMetal flavorizer bars durable?

These bars are fabricated from 16‑gauge steel and covered with a porcelain enamel finish. The thicker 16GA material resists warping and offers longer life than thinner 17GA or 20GA replacements, while the enamel layer adds corrosion resistance and simplifies cleaning.

• Robust 16GA steel core for strength under high heat.
• Porcelain-enamel coat reduces sticking and eases maintenance.
• Designed to withstand repeated heating cycles without deforming.

How do these heat plates affect cooking performance and flavor?

Flavorizer bars act as heat shields and flavor amplifiers—catching drippings, preventing flare-ups, and turning juices into vapor that flavors food. QuliMetal bars provide stable heat distribution across the grill, which helps achieve more consistent searing and even cooking from front to back.

• Vaporizes drippings to recreate smoky, grilled aromas.
• Shields burners from direct flame, reducing hot spots and flare-ups.
• Results in more uniform temperature across the cooking surface.

How easy is installation and upkeep for these replacement bars?

Installation is a simple swap: lift the cooking grate, remove old bars, and set the QuliMetal replacements in place. The porcelain finish cleans with a grill brush or mild cleaner; occasional inspection for chipping or heavy corrosion will keep the system working well.

• Tool-free installation in most Genesis II/LX 300 models.
• Brush off char and debris after use to prolong finish life.
• Replace as a matched set to maintain balanced heat and protection.

Who is this for: Home grillers and barbecue enthusiasts with a Weber Genesis II or LX 300 series (2017 and newer) who want a reliable, OEM‑sized replacement that improves heat distribution, reduces flare‑ups, and restores the grilled flavor they expect. Choose QuliMetal GS4 Flavorizer Bars if you prefer thicker, longer‑lasting steel and a porcelain‑enameled surface for easier cleanup and consistent performance.
