NTK O2 SENSOR CALIBRATED FOR HOLLEY HP AND DOMINATOR (M1 Boosted calibration)

Mad Racing developed a replacement NTK oxygen sensor for Holley Dominator and HP. Each one is individually calibrated and then live tested to your Lambda requirement.

Wire length on this sensor is 16" so be sure you have enough slack in your main harness to reach. The OEM Holley sensor has extensions added and comes in at 25". OUR SENSOR CABLE IS 10" SHORTER

We use these sensors in all our turbo M1 builds.
