Add on Silicone Insulation Tubing for Numeric Racing cables.
For those who are concerned of any slight noise or vibrations from the metal cable ends that provide the durability of the cables.
Some hear a slight vibrations, others do not.
This is a great solution to cover up any add-on noise.
Instructions: Cut the tube in a spiral so that you don’t need to use any zip ties to hold it on. One twist per foot will work just fine. It is also important that you reuse the rubber grommet that hold the cables in the firewall.
