Hongso Flavorizer Bars for Weber Spirit 300 Series — 5-Pack 15.3-inch Stainless-Steel Heat Plates, Even Heat

Hongso replacement flavorizer bars — a set of five 15.3-inch stainless-steel heat plates designed to protect burners and promote even cooking on compatible Weber Spirit 300-series grills.

These Hongso Flavorizer Bars are made to replace worn or damaged heat plates on specific Weber Spirit 3-burner grills (models from 2013–2017 and Spirit II 300 Series). They shield burners from drippings, help vaporize juices for added aroma, and create a more even heat profile across the cooking grate. Before ordering, confirm your grill’s model year and that the control panel is front-mounted — these 15.3" bars will not fit Spirit 300 grills with side-mounted controls or older Spirit 200-series units.

Which Weber models are these Hongso bars compatible with?

How do these stainless-steel heat plates improve grilling performance?

Hongso bars divert drippings away from the flame to reduce flare-ups and protect burners from corrosion. They convert drippings into flavorful smoke, producing more consistent heat across the grill and helping food cook more evenly without hot spots.

• Reduce flare-ups by channeling grease away from direct flame.
• Generate vaporized drippings that enhance grilled flavor and aroma.
• Even out heat distribution across three-burner configurations.
• Protect burners from drippings and extend burner life.

What are the dimensions and material details of the Hongso bars?

Each set contains five stainless-steel Flavorizer Bars measuring 15.3 inches long, 2.6 inches wide, and about 2.5 inches tall. They are manufactured from stainless steel for durability and rust resistance; note that certain stainless grades can be magnetic due to iron content.

• Set of 5 bars, each 15.3" x 2.6" x 2.5" (length x width x height).
• Constructed of stainless steel for strength and heat tolerance.
• Intended size: 15.3" — not compatible with 21.5" or 22.5" bars.
• Magnetism: stainless steel may be magnetic depending on alloy composition.

How do I confirm fit before buying Hongso replacements?

Verify your Weber grill’s series, model year, and the location of the control panel. If your Spirit 300 has side-mounted controls or is from the 2007–2012 era, these 15.3" bars will not fit. Refer to your grill’s manual or the model number printed on the grill for exact confirmation.

• Check your grill model: Spirit E-310, S-310, Spirit II 300 series, etc.
• Confirm control panel position is front-mounted (not side-mounted).
• Compare existing flavorizer bar length to 15.3" before ordering.
• Review listed compatible Weber part numbers if available.

Who is this for? These Hongso stainless-steel flavorizer bars suit grill owners who need direct replacements for worn heat plates on compatible Weber Spirit 3-burner grills (2013–2017 and Spirit II 300 series). They are ideal if you want to reduce flare-ups, protect burners from drippings, and restore even cooking without replacing the entire grill. Do not buy if your grill uses longer bars or has a side-mounted control panel; confirm fit first to ensure reliable performance.
