That stuff you linked looks pretty good. My wideband cable was long enough to go across to the drivers' side, then up against the firewall & back across thru the battery compartment. Where it passed anything remotely hot, I folded strips of the stick-on aluminium heat shield around the cable - the same stuff as I bought to stick above the dump pipe & cat etc. It's not overly pretty, but can't be seen anyway. I have a feeling that the cable it fairly robust & resilient to heat (within reason), but I didn't want to risk it melting. If you look at where the stock oxy sensor cable goes (close to turbo & manifold) you may not be too concerned about your new one.
