PERRIN Firewall Grommet, 1.4" (2015-2017 Impreza WRX & WRX STi)

EASY AND CLEAN CABLE MANAGEMENT
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.

PROTECT WIRES FROM WEARING THROUGH
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.
