Genesis II Flavorizer Bars & Heat Deflectors Replacement - Fits 300

In this review the Genesis II flavorizer bars and heat deflectors from QuliMetal are evaluated as a direct replacement option for Weber Genesis II 300 series grills. The bottom line: this set is for grill owners who need a durable, well-fitting replacement that restores even heat distribution and protects burners from drips. The reviewer found the set simple to install and appreciated the heavy porcelain steel construction and the specific dimensions that match common Genesis II 300 models, making it an easy repair for routine maintenance.

Key Features

• Exact fit: The flavorizer bars measure 17 1/8 in x 3 in x 2 1/8 in and the heat deflectors measure 12.5 in x 4.25 in, providing a precise match to the original parts for easy replacement.
• Complete set: Includes five porcelain steel flavorizer bars and three porcelain steel heat deflectors so a full burner row is covered in one purchase.
• Porcelain steel durability: Constructed from high-quality porcelain steel for improved resistance to wear and longer service life compared with thinner alternatives.
• Snow point coating: QuliMetal's snow point porcelain finish resists high heat and reduces flaking over time, helping maintain appearance and performance.
• Heat management: The bars and deflectors prevent direct flame contact, distribute heat evenly, and shield burners from drips to improve cooking consistency.
• Care guidance: Simple long-term storage tip included: coat with cooking oil and wrap to prevent rust between seasons.

Who It's For

The set is ideal for owners of Weber Genesis II 300 and compatible LX 300 series grills who need direct replacements for worn or damaged flavorizer bars and heat deflectors and want a durable porcelain steel option. It suits people who prefer a near-original fit and who want to keep burners protected and heat distribution consistent.

It is less suited to owners of older or non-Genesis II models that use different sized parts, or to users who prefer stainless steel or alternative materials; confirming original part dimensions and model year (2017 and newer compatibility noted) is recommended before ordering.
