The Firewall Grommet 2-4 Gauge by QUICKCAR Racing Products is an essential component for both professional and amateur automotive builders who need to route electrical harnesses through the vehicle firewall. This grommet provides a clean and protected passage for battery cables, alternator wiring, and starter leads, ensuring that the metal is not damaged and sharp edges do not compromise insulation.
Constructed from molded rubber, this grommet seals the firewall opening while allowing for flexible routing of heavy-duty electrical conductors. It is designed to withstand under-hood heat cycles, engine vibration, and occasional contact with coolant or oil, making it a reliable choice for both motorsports and street applications.
Builders working on custom battery systems, relocated fuel pumps, auxiliary fuses, or high-amperage circuits will find this grommet indispensable. Its compact size of 3.5 x 1.55 x 4.5 inches fits most firewall openings common to mid-size and full-size vehicles, ensuring compatibility across a range of applications.
