Protect your shifter cables from melting and burning with K-Tuned Heat shield Tubing. These 4 foot long and ID tubes are constructed with an aluminized outer layer that is laminated to a braided fiberglass insulation that provides superior protection from radiant heat up 1400 degrees Fahrenheit. Each tube split down the middle so it can be put on the cables even when they are already installed on the vehicle. This is a very simple product that solves a simple problem. Please note that the shifter cables still need to be properly fastened away from the header and other exhaust piping.
