Throw away those leaky rubber grommets! Daystar’s Firewall Boot is the BEST way to run wires, hoses, and other lines through your vehicle’s firewall. Simply drill a 1.25” diameter hole in the firewall and install the boot. Run your wires, trim the boot as necessary, and secure the assembly with a zip tie. It’s that easy!


  • Safely and cleanly run wires through firewalls and bulkheads
  • Protects wires from sharp edges
  • Eliminates air / water leaks 
  • Prevents wire chaffing and shorts
  • Fits a variety of wire thicknesses and bundles from 3/8” to 1”
  • Works great for tubing and air lines, too!
  • 1.25” diameter hole required for installation.
  • A must have for lighting and gauge installations!
