An ethanol content sensor that reads the fuel's ethanol percentage and sends that signal to a supporting ECU or tune, letting the truck run E85 blends safely.
why this one — It is the barb-fitting version of AEM's flex fuel sensor kit at $236.95, from an established electronics brand. It only pays off as part of a tuned ethanol setup, so check local fuel rules and warranty impact first.
No HP claim - sensor outputs a 0-100% ethanol reading via frequency signal (50Hz=0%, 150Hz=100%) for a supporting ECU to use.
Fuel system hardware is not itself an emissions-control component, but running on E85/high-ethanol blends requires supporting tune changes - verify local fuel regulations and powertrain warranty impact before installing.
