PERRIN Subaru WRX 15-21 / Universal Fire Wall Grommet - 1.4in.

Perrin Performance is known for making well-built aftermarket parts for Subarus, and this firewall grommet is no exception. If you're running extra wiring through your Subaru WRX's firewall, like for gauges, boost controllers, or audio equipment, you need a clean way to seal up those holes. This grommet from Perrin is designed to do just that, helping to keep dirt, water, and engine bay heat out of your cabin.

This grommet is made from a durable rubber material that can handle the heat and vibration found in the engine bay. It features a 1.4-inch opening, which is a common size for passing through various wires and cables. Installing it is straightforward: you typically push it into a pre-drilled or existing hole in the firewall, and then route your wires through the center opening. It's a simple part, but it makes a big difference in keeping your wiring tidy and your interior protected.
