If your Weber Spirit E-/S-300 series grill needs new cooking grates or the original flavorizer bars are worn, this Dictirdy replacement kit gives you professional-style cast iron searing surfaces plus durable porcelain-steel vaporizers engineered to restore reliable heat distribution and protect burners. The components were designed to match the common measurements for 3-burner Spirit 300 and Spirit II 300 models made from 2013 onward, offering a straightforward swap for owners who want better sear marks, longer-lasting parts, and improved smoke flavor without replacing the whole grill.

Will these parts fit my Weber Spirit E-310, E-320, S-330 or Spirit II 300 series?

• Always confirm by measuring your grill’s current grates and bars prior to purchase.

How do the cast iron grates and porcelain flavorizer bars change grill performance?

Cast iron holds and radiates heat effectively to create clear sear marks and even cooking across the surface, while porcelain-coated flavorizer bars redirect drippings to create smoke and protect burners from flare-ups. Together they improve thermal consistency, extend burner life, and boost the savory aroma typical of grilled food.

• Cast iron accelerates heating and delivers pronounced sear lines.
• Porcelain-coated steel resists corrosion and withstands high temperatures.
• Flavorizer bars vaporize juices to add smoky notes and reduce direct flame contact.
• Heavier gauge materials last longer than many thin replacement parts.

What materials and care do these replacement parts require?

The cooking grates are solid cast iron for robust heat retention; the flavorizer bars are 100% food-grade steel with a porcelain enamel finish for corrosion resistance. Proper seasoning, cleaning, and storage will preserve performance and extend service life.

• Season cast-iron grates with a thin oil coat before first use and after deep cleaning.
• Clean porcelain bars with a grill brush and mild detergent; avoid abrasive metal tools that chip enamel.
• Inspect bars for chips or heavy rust; replace if protective coating is compromised.
• Store parts dry when not in use to prevent corrosion.

What comes in the package and what should I check before installation?

This kit contains two cast iron grill grates and five porcelain-coated steel flavorizer bars sized to match the Spirit 300 two-grate footprint and one-bar row layout. Verify your grill’s grate dimensions and the number/placement of flavorizer bars to ensure a correct fit.

• Includes: 2 cast iron grates (17.5" x 11.9" each) and 5 porcelain flavorizer bars.
• Compare lengths and mounting clearance with your existing parts before installing.
• Follow safe installation: disconnect propane/turn off natural gas and allow grill to cool fully.
• Confirm burner alignment and that bars sit level over the burners for even heat.

Who is this kit for: Grill owners of Weber Spirit 300 and Spirit II 300 series (front-control, three-burner models) who want a cost-effective way to restore searing performance, reduce flare-ups, and extend the life of the grill’s burners. It’s suited for backyard cooks who value stronger heat retention and a more authentic grilled flavor without replacing the base unit.
