Revhigh’s heavy duty O2 extension harness is built to give your vehicle the very best signal when using aftermarket headers!

We include a layer of aluminium covering around EACH wire and then again around the whole wire loom itself before being wrapped in heatproof plastic.

As mentioned earlier, aluminium is used in 2 stages to prevent the signal from being interfered.

We’ve found that cheap O2 extenders can cause engine lights, incorrect fuel trim data and poor fuel consumption.

Please refer to the picture attached showing the difference between aluminium and non-aluminium coated.
