- Works with unleaded gasoline, alcohol, propane or nitrous oxide

A computer controlled electronic fuel injection system uses an oxygen sensor to signal the computer the status of the air / fuel mixture. The sensor samples the oxygen level in the exhaust and sends this information to the computer. The computer then recalibrates the fuel delivery system, thousands of times per second, to maintain the proper air/fuel ratio throughout the entire rpm range.
The same technology is used in the K&N Air / Fuel Ratio Monitor. An oxygen sensor measures the amount of oxygen in the exhaust gas and illuminates a group of LED lights indicating the actual air/fuel mixture: lean, rich or just right. Using the K&N Monitor, you can adjust the mixture for peak performance, economy or drivability. It can also be used to prepare a vehicle for emissions testing or as a piece of dynamometer test equipment. An oxygen sensor can also be installed in both exhaust pipes of a V-type engine to check fuel distribution. The Monitor can then check either bank with the flip of a switch (switch not included).
The K&N Air / Fuel Ratio Monitor comes complete with everything necessary for installation including detailed instructions.
Note: The K&N Air / Fuel Ratio Monitor is not compatible with leaded gasoline, nitromethane or diesel fuel.199.99
