Wireless Ethanol Analyzer Kit & 10 Micron Filter — [M157]
$569.00
An ethanol content analyzer so you know the real blend in the tank rather than guessing from pump labels. Ethanol percentage varies station to station, and a flex calibration is only as safe as the number it is working from.
Fitment
Mercedes-AMG M157 platforms
- Accurate real-time ethanol reading
- Takes the guesswork out of blending
- Recommended for any flex-fuel build
