Our take
The verdict
The Denso 234-5030 Air Fuel Sensor keeps its spec sheet short, which suits getting a generator back in working order. No buyer reviews yet, so this Denso replacement part has to win you over on paper. The catch with the Denso: no word on the exact fit. We'd pick it if you want a replacement part for getting a generator back in working order; otherwise, put it next to the Anxingo Fuel Filter for Generac first.
