I've run across many cases where that's not true. Especially on high-compression or boosted engines. The compressed mixture is much more difficult to ionize and jump compared to plain air. Even factory ignition-systems that work fine with stock motor, ends up failing to ignite when exact same engine gets higher-compression pistons or boost.
