PETKAO Spirit II 300 Replacement Grill Parts Kit for Weber E310/E320/S310/S320 — Porcelain-Enamel Flavorizer Bars & Burners

Complete replacement kit containing porcelain-enameled flavorizer bars, three main burners, a crossover burner and a stainless heat deflector made to fit Weber GS4 Spirit II 300 Series (E310/E320/S310/S320) models from 2017 and newer.

When a Spirit II grill shows uneven heat, rusted flavorizer bars, or a weak flame, replacing worn components restores performance without buying a whole new grill. This PETKAO kit bundles the common GS4 Spirit II 300 Series service parts you’ll need: five snowflake-point porcelain-enameled flavorizer bars, three full-length main burners plus a shorter crossover burner, and one stainless steel heat deflector. Each component matches the dimensions and mounting patterns used on Weber Spirit II models with up-front control so installation is straightforward for homeowners and grill techs alike.

What are the exact dimensions and materials included?

Knowing measurements helps ensure the parts will drop into place. PETKAO supplies clear dimensions for each element so you can compare them to your grill’s originals before ordering.

• Flavorizer bars: five pieces, each 15.3 x 2.6 x 2.5 inches, 16-gauge snowflake-point porcelain-enameled steel.
• Main burners: left and right 18" (45.72 cm), center main burner 17-3/4" (45.09 cm).

How do these replacement pieces improve grill function and upkeep?

Replacing corroded burners and flavorizer bars restores even heat distribution, improves ignition reliability, and reduces flare-ups. The porcelain-enameled flavorizer bars shed drippings into vapor that enhances smoke flavor while protecting burners beneath.

• Thicker snowflake-point porcelain enamel resists chipping and rust for longer life.
• Full-length burners restore consistent flame pattern across all three burners.
• Stainless heat deflector directs heat and shields the grill body from drips and flames.
• Visible cutouts in the flavorizer bars make it easier to check burner flame during lighting.

How easy is installation and what tools are typically needed?

Installation is designed to be a homeowner-friendly maintenance task that most people can complete in under an hour. The parts match Weber mounting points and require only basic hand tools to replace safely.

• Typical tools: screwdriver, socket set, work gloves, and a flashlight for inspection.
• Remove old flavorizer bars and burners, slide new burners onto the gas ports, and secure with existing hardware.
• No gas-line modifications are required when replacing like-for-like GS4 burner tubes.
• Inspect valves and igniter components while the grill is open; replace any worn fasteners if necessary.

Who is this kit for? PETKAO’s replacement set is aimed at Spirit II owners who want a cost-effective repair and refresh of their GS4 300 Series grill rather than buying a new unit. It’s well suited for adults who maintain backyard grills, homeowners preparing for heavy seasonal use, rental property managers, and any barbecue enthusiast looking to restore even heating, safer operation, and a cleaner grilling surface. If your Spirit II shows rusted flavorizer bars, uneven burner flames, or you’re prepping for a busy grilling season, this kit supplies the matched parts and dimensions to get your grill back to reliable service.
