How to Choose

What Research and Testing Say About Ignition Reliability

Scientific testing and independent lab evaluations highlight several factors that determine ignition system performance: spark energy and consistency, electrode material and coating, correct electrode gap and alignment, weather and corrosion resistance, and the electronic reliability of control modules. Studies and industry test results show that modern electronic ignition modules and well-designed electrode assemblies reduce misfires and improve safety by delivering repeatable sparks with lower power draw and better protection against environmental wear.

Higher and more consistent spark energy reduces failed ignition attempts and lowers the chance of gas build up before lighting.

Corrosion-resistant electrode materials and protective ceramic supports extend service life, especially in wet or coastal conditions common in parts of Canada.

Proper electrode gap and placement are critical; small deviations significantly increase ignition time and misfire rates.

Electronic ignition modules can offer improved sequencing, diagnostic features, and lower battery drain compared with older or poorly designed systems.

Piezo igniters are simple and highly reliable mechanically, but electronic systems often provide better long-term diagnostics and integration with modern RV control panels.
