The Best Grill Igniters

The main difference lies in their power source and spark generation. Piezo igniters, like those from BTFO or Gosknor, are mechanical, generating a spark from a crystal under pressure, thus requiring no batteries. Electronic igniters, such as the GasSaf Spark Generator, use a battery (typically AAA) to create a consistent, multi-point spark via an electronic circuit.

You need to count the number of ignition points or burners on your grill that require a spark. A 1-outlet igniter, common for single-burner applications, will only provide a spark to one electrode. If your grill has two or more burners that ignite electronically, like many models compatible with the GasSaf 2 Outlet Spark Generator, you'll need an igniter with at least that many outlets.

Igniter wires are commonly made with ceramic insulation and a metal conductor, as seen in BTFO and Gosknor products. Ceramic is crucial because it insulates against high temperatures and prevents the spark from grounding prematurely. The metal conductor ensures efficient transmission of the spark from the igniter module to the electrode, which is vital for consistent ignition.

While some universal igniters might technically produce a spark, they often lack the specific fitment and ignition chamber design required for optimal performance in Weber Genesis or Spirit grills. For these models, a dedicated kit like the onlyfire Igniter Kit for Weber Spirit Genesis is typically recommended, as it's engineered to match the original specifications and ensure reliable ignition.

The length of the spark plug wire is critical for proper installation and function. If the wire is too short, it won't reach the burner electrode, and if it's too long, it can be difficult to route safely and might interfere with other components. Always measure your existing wire or check the specifications of your grill, noting that products like Aupoko's Double Ignition Kit specify a 450 mm wire length.
