The PERRIN Firewall Grommet makes cable management for routing wires from the interior to the engine bay simple and protects them from wearing on bare metal.
Allows for an easy pathway to route cables, wires, and hoses between your engine bay and interior. This makes for a more professional installation when installing PERRIN Gauges.
When you install your wires to connect whatever sensors you may have through to your gauges on your dash, you will have to get them through the firewall somehow. Without the PERRIN Firewall Grommet, the wires can rub against sharp metal edges in the firewall, causing them to wear through. Keep solid and clean connections with the PERRIN Firewall Grommet.
