PERRIN Firewall Grommet 2015-2021 WRX

Keep solid and clean connections with the Perrin Firewall Grommet. When you install your wires and hoses 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. The grommet will help prevent this kind of problem. Sold individually.

Fits all 2015-2021 WRX.
