QuliMetal Flavorizer Bars for Weber Spirit 300 & Spirit II 300 — 15.3" Porcelain 5-piece, 16-gauge Heat Plates

These QuliMetal 15.3" porcelain-coated flavorizer bars replace part 7636 to protect burners and boost smoky flavor on Weber Spirit 300 and Spirit II 300 series grills.

Replacement heat plates wear out faster than most grill owners expect; QuliMetal engineered a set of five robust 15.3 x 2.6 x 2.5 inch flavorizer bars specifically for Weber Spirit 300-series grills and Spirit II 300 models. Made from heavier 16-gauge steel with a high-temperature snow-point porcelain finish, these bars are built to resist chipping, shield burners from drips and flare-ups, and help vaporize drippings to add grill flavor. The set is intended as a direct-fit replacement for part number 7636 and covers many Spirit E-310, S-315, E-320 and Spirit II variants.

Will these flavorizer bars fit my Weber Spirit 300 or Spirit II 300 grill?

Yes — they are tailored for three-burner Spirit 300-series models with front-mounted controls and for Spirit II 300 grills. Measure for 15.3 inch length across your existing heat plates to confirm compatibility if you have a non-standard setup.

• Fits Spirit E-310, E-315, E-320, S-310, S-315, S-320 models
• Compatible with Spirit II E-310/320 and S-310/320 3-burner grills
• Direct replacement for part number 7636
• Set contains five bars sized 15.3 x 2.6 x 2.5 inches

How durable are these QuliMetal heat plates compared with stock bars?

These bars are made from heavier 16GA steel versus common 17GA or 20GA aftermarket options, so they resist bending and last longer under regular high-heat grilling. The snow-point porcelain coating is formulated to better withstand temperature cycles and reduce surface chipping compared to plain paint finishes.

• 16-gauge steel core for structural strength
• High-temperature porcelain to limit chipping and corrosion
• Designed for repeated heating and cooling without warping
• Protects burners from grease and reduces flare-ups

What cooking benefits do these flavorizer bars provide?

By catching drips and vaporizing juices, the bars create aromatic smoke that enhances seared foods without direct flame contact. They also channel grease away from burners, which reduces hot spots and improves the grill’s heat distribution for more consistent cooking.

• Vaporizes drippings to add subtle smoke flavor
• Reduces flare-ups by shielding burners
• Helps even out heat across the cooking grate
• Easy swap-in replacement to restore grill performance

How do I install and maintain these replacement bars?

Installation is a straightforward remove-and-replace job: lift the cooking grate, slide out old bars, and set the QuliMetal bars into the same slots. Maintain them by brushing after cool down and avoid harsh scraping to preserve the porcelain layer; replace as needed when heavy corrosion appears.

• Lift grates, slide old bars out, insert new bars in same orientation
• Clean with a grill brush after cooling to preserve coating
• Inspect annually for rust or severe chipping
• Replace bars in matched sets for even heat performance

Who is this for: Grill owners with three-burner Weber Spirit 300 or Spirit II 300 series grills who want a durable, direct-fit replacement for worn flavorizer bars. This five-piece QuliMetal set suits anyone repairing an original 7636 kit, upgrading to thicker steel, or restoring even heat and better smoke flavor without modifying their grill.
