Spirit E310 Grill Parts Replacement Grates & Flavorizer Bars - Durable

Our review of these Spirit E310 grill parts finds them best for owners of Weber Spirit 300 and Spirit II 300 series grills who need a straightforward, durable replacement for worn cooking grates and flavorizer bars. The single biggest reason to buy is simple: these replacement parts match the original dimensions and materials closely enough to restore searing performance and protect burners, while the porcelain-enamel finish makes cleanup noticeably easier. Installation is straightforward and customers report a snug, correct fit on front-control Spirit models.

Key Features

• Exact compatibility: Designed for Weber Spirit 300 and Spirit II 300 series grills so buyers can expect parts that fit models with front-mounted controls.
• Porcelain-enameled cast iron: The grates combine cast iron heat retention with an enamel surface that resists rust and reduces the need for constant seasoning.
• Flatter top design: Wide flat slats and smaller gaps keep food from slipping through and improve searing contact with the grates.
• Durable flavorizer bars: 20GA thick steel flavorizers with a shiny black enamel resist deformation and protect burners while vaporizing drippings for smoky flavor.
• Easy cleaning: Smooth enamel finishes on both grates and flavorizer bars make residues easier to remove with a brush and soapy water.

Who It's For

These parts are for owners of Weber Spirit E-310, E-315, E-320, S-310, S-315, S-320 and compatible Spirit II 300 series grills who want a cost-effective way to replace worn grates and flavorizer bars without changing cooking performance. They suit grillers who value good searing from cast iron and want parts that are easy to clean.

Not ideal for someone who wants stainless steel grates, a different grate pattern, or a custom cooking surface; also check original part dimensions before ordering to ensure the 17.5 in grates and 15.3 in flavorizer bars match your model.

Frequently Asked Questions

Will these fit my Spirit E-310 grill?
Yes, they are made to fit Weber Spirit E-310 and compatible front-control Spirit 300 series models, but compare the listed grate and bar dimensions with your originals before buying.

Are the grates pre-seasoned?
The cast iron grates come pre-seasoned and have a porcelain-enamel surface so they do not require the same frequent seasoning as bare cast iron.

How do I clean the flavorizer bars?
Use a grill brush and soapy water - the shiny enamel finish resists sticking, so residues usually scrub off easily.
