The kit includes the following:

*If you aren’t sure whether this kit fits your car, send us a picture of your engine bay with the engine cover removed to sales@

*Ethanol Sensors don’t actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated.
