Haltech Firewall Rubber Wiring Grommet

This Haltech firewall rubber wiring grommet is what you get when you order part number HT-039005. It's a well-built rubber piece designed to help seal openings in your vehicle's firewall where you're passing wiring through. Keeping your engine bay sealed up helps prevent dirt, moisture, and fumes from entering the cabin, which is especially important when you're running custom wiring for aftermarket engine management systems or other accessories.

Using a proper grommet like this one not only helps maintain a cleaner engine bay and interior but also protects your wiring from abrasion against sharp metal edges on the firewall. This can help prevent shorts or damage to your electrical system over time. It’s a simple but effective part for any custom fabrication project where you need to route wires cleanly and safely through the firewall.
