MAD Racing NTK O2 sensor calibrated for Holley HP and Dominator (Oxygen Sensor)

Part #: MADO2-.6

Brand: MAD Racing Parts



We have 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.

All sensors are the same "calibration", we test and verify each one to be dead on at the Lambda you order.

This means for example, a .6 sensor is STILL ACCURATE at .9


Suggested target Lambda to order for most common applications-

Boosted methanol use  .6

Boosted E85 use  .7

Boosted gas use  .8 

NA (ALL fuels) .9 

Nitrous Apps .9
