Genesis II E-310 Flavorizer Bars & Heat Deflectors - Even Heat, Better

In this review the Genesis II E-310 flavorizer bars and heat deflectors are evaluated as a direct replacement set for Weber Genesis II 300 and LX 300 series grills. The bottom line is that this kit is for grill owners who need a straightforward, durable way to restore even heat distribution and recover smoky flavor; it replaces worn or missing heat plates with porcelain enameled steel parts that resist grease and vaporize drips back into the cooking chamber to enhance taste. Installation is simple and the set targets common hot and cold spot issues.

Key Features

• Porcelain enameled steel: The upgraded finish resists corrosion and holds up to high temperatures while remaining easy to clean.
• Even heat distribution: The bars and deflectors spread heat across the cooking area to reduce hot and cold zones for more consistent grilling.
• Grease management: Parts cover the burner tubes to catch oil drips and vaporize them at high heat to return smoky flavor to food.
• Complete replacement set: Includes five flavorizer bars and three heat deflectors so users replace an entire bank at once for matched performance.
• Model compatibility: Designed to fit Genesis II 300 and LX 300 series models from 2017 and newer, covering many e-310, e-315, e-335 and related variants.

Who It's For

This kit is best for owners of Genesis II 300 series and Genesis II LX 300 series grills (model years 2017 and newer) who notice uneven cooking or visible wear on existing flavorizer bars. It is a practical option for backyard cooks who want to restore smoky flavor and consistent heat without changing burners or major components.

It is not for owners of Genesis 300 series grills made before 2017 or for people who need parts outside the 300/LX 300 family. If a grill requires different sized plates or non-porcelain finishes, those users should look for model-specific parts instead.
