Since founder Vic Edelbrock Sr. began building performance intake manifolds in 1938, Edelbrock has grown into one of the most trusted names in American high-performance parts, from carburetors and intake manifolds to cylinder heads, crate engines, and EFI systems. JEGS has spent decades supplying Edelbrock components to racers, engine builders, and street enthusiasts, backing this extensive lineup with in-house technical support, fast shipping, and a Price Match Guarantee so you can choose proven Edelbrock parts with confidence.
This air/fuel monitor consists of an O2 sensor and a calibrated electronic display. Simply install the O2 sensor in the exhaust pipe, and then connect the display. When the engine is running, the actual air/fuel ratio is continuously displayed. The monitor indicates air/fuel ratios from approximately 12 to 15. Use it to guide carburetor adjustment and jetting or to improve ignition spark advance curves. Not recommended for use with leaded fuels.
