Features

FlameSelect Precision Cooking

With 9 distinct power levels, FlameSelect lets you dial in exactly the right flame intensity every time, giving home cooks the kind of repeatable, restaurant-quality control that makes a real difference from a gentle simmer to a high-heat sear.

OptiSim Burner for Delicate Dishes

The dedicated OptiSim burner delivers an ultra-low, even simmer ideal for melting chocolate, warming sauces, or slow-cooking without the risk of scorching, making this cooktop a smart upgrade for anyone who loves precision in the kitchen.

37-Inch Width Built for Serious Kitchens

At 37 inches wide with a 34 15/16 inch cutout requirement, the NGM8658UC fits naturally into design-forward kitchens and open layouts, offering generous multi-burner surface space for busy families or home entertainers who cook multiple dishes at once.

Why You'll Love It

The Bosch NGM8658UC is a 36-inch, 6-burner gas cooktop built for home cooks who want professional-level flame control and a refined kitchen presence. With FlameSelect technology and a dedicated OptiSim burner, it offers a meaningful upgrade over standard 4-burner cooktops without requiring a full range replacement.

  • A compelling step up for cooks moving from a basic 4-burner surface to a full 6-burner 36-inch layout with precision flame control.
  • Fits a standard 34 15/16" x 19 1/8" countertop cutout, making installation straightforward in most existing 36-inch kitchen openings.
  • FlameSelect delivers 9 distinct power levels per burner for reliable, repeatable heat whether you are searing, sauteing, or slowly melting chocolate.
  • Ideal for design-forward kitchens that want stainless steel durability paired with heavy-duty cast iron grates and a low-profile, sleek surface.

NGM8658UC: Precision at Every Burner

Six burners across a 37-inch stainless steel surface give the NGM8658UC real cooking range, while FlameSelect and the OptiSim burner make it one of the most controllable gas cooktops in its class.

  • 6-burner layout on a 37" overall width (34 15/16" cutout width) designed for versatile multi-pot cooking sessions.
  • FlameSelect technology provides 9 precise, numbered power levels per burner for consistent and repeatable flame settings across every cook.
  • OptiSim burner delivers ultra-low simmer heat without cycling on and off, making it ideal for delicate sauces, chocolate, and slow-cooked dishes.
  • Heavy-duty cast iron grates offer a stable, durable cooking surface that supports large and heavy cookware across all six positions.
  • Brushed stainless steel surface resists everyday wear while contributing a professional, sleek look that integrates with modern kitchen cabinetry.
