PETKAO Weber Spirit II E310 Grill Replacement Kit — Porcelain Flavorizer Bars & Cast‑Iron Grates

PETKAO's complete replacement kit refreshes a Weber Spirit II E310 by supplying porcelain-enameled flavorizer bars, matte cast-iron grates, a stainless heat deflector and a four-piece burner tube set engineered to restore cooking performance.

Whether your Spirit II 300 Series grill is showing rust, uneven heat, or clogged components, this PETKAO kit supplies the most commonly worn parts to bring it back to reliable service. All pieces are sized to match Weber GS4 Spirit II models (including E310/S310/E320/S320, model years 2017 and later) and replace multiple Weber part numbers so you can swap worn components without buying separate items.

How will these replacement flavorizer bars and grates affect grilling performance?

The kit’s upgraded snow-point porcelain-enameled flavorizer bars and matte cast-iron grates help stabilize heat distribution and improve searing. Porcelain coating resists flaking and corrosion, while cast iron holds heat for better crust development on steaks and burgers.

• 5 porcelain-enameled flavorizer bars, each 15.3 x 2.6 x 2.5 inches, 16GA thickness for durability
• 2 matte cast-iron grates, 17.5 x 11.9 inches for consistent heat retention
• Flavorizer bars include four notches for improved ventilation and even heating

Will the burner tubes and heat deflector restore even heating?

Yes — the burner tubes are sized to replace the original left, right, center and crossover burners, producing a more even, efficient flame when adjusted properly. The stainless steel heat deflector reflects heat back to the cooking surface and captures drippings to create beneficial smoke without clogging the burners.

• Burner lengths: left/right mains 18", center main 17.75", crossover 15.25"
• Stainless heat deflector with mounting tabs and three slotted vents for controlled airflow
• Simple air intake adjustment helps achieve a steady blue flame

How do I know this kit fits my Weber Spirit II model?

The PETKAO kit lists compatibility with a wide range of Weber original part numbers and Spirit II model identifiers, covering many Spirit II E310/S310 and related serials. To avoid ordering the wrong component, measure your current parts and compare model numbers before installing.

• Fits Weber Spirit II 300 Series models (E310, S310, E320, S320) from 2017 onward
• Compatible with multiple Weber part numbers for flavorizer bars, grates, burner tubes and heat deflectors
• Package includes all pieces needed to replace common wear items in one purchase

Who is this for?

This PETKAO replacement kit is aimed at Spirit II owners who want a practical, all-in-one solution to restore their grill’s heat control and cooking surface without sourcing multiple OEM parts. It’s ideal for backyard grillers who prefer a durable porcelain finish and heavy cast-iron cooking grates, plus DIYers comfortable swapping burners and panels for improved performance.
