COMVIEE Heat Manifold Replacement Kit for Masterbuilt Gravity Series 560 MB20040220/MB20041020 — Heavy-Gauge Steel, OEM Fit

COMVIEE's Heat Manifold Replacement Kit restores even, predictable heat across Masterbuilt Gravity Series 560 grills so you can cook like new again.

If the internal heat distribution component of your Masterbuilt Gravity Series 560 (models MB20040220 or MB20041020) has warped, corroded, or failed, this direct-fit COMVIEE replacement is engineered to match OEM form and function. Built from heavy-gauge steel, the manifold helps spread charcoal heat more evenly under the cooking chamber, stabilizes temperature behavior, and removes a common cause of hot spots. The kit is designed for a straightforward swap so you spend less time troubleshooting and more time grilling.

How will this manifold affect cooking performance?

Replacing a damaged manifold restores the grill’s original airflow and heat pattern, reducing temperature variance across the cooking grates. You’ll notice fewer sudden spikes or cold zones, which makes timed recipes and multi-rack cooking more consistent. Better distribution also helps charcoal burn more efficiently.

• Re-establishes balanced heat from center to edges
• Reduces hot spots and uneven doneness
• Improves charcoal combustion efficiency
