Perrin 1.4″ Fire Wall Grommet – 2015-2021 Subaru WRX & WRX STi


Installation Instructions & Videos

Installation Instructions

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.

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.

Easy & 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.

*Sold as a single Grommet
