The Wideband Air/Fuel Ratio Meter will allow you to more precisely tune your engine. Programmable warnings will tell you if your engine is too lean or rich. Works with both 2 and 4 stroke engines. To avoid sensor contamination with a 2 stroke an adapter (16-205) needs to be used, in those applications the hole must face the piston. Kit is complete for 4 stroke use, order 2 stroke adapter separately. Requires 12V power. **TEMPORARY TARIFF INCREASE** Please note that this item is under a temporary price increase due to tariffs and will be reduced as soon as we are able
