Firewall Wiring Push-Through Adapter Billet Aluminum

Billet aluminum. The firewall detail people notice. A bundle of wire shoved through a bare hole in sheet metal is how good builds get let down. The edge cuts insulation; the grommet falls out in a year; and the whole firewall reads unfinished. This adapter is two pieces of machined billet that sandwich over the opening and clamp the pass-through solid. It does not care about heat or vibration; and it still looks like it belongs three years later. Machined raw or black Cerakote. It is cut to pair with our F100 Coyote Swap H-Pipe Bulkhead Adapter Kit so the firewall reads as one set of parts rather than three vendors. One honest note. No bore size; wire capacity or seal material is published on this listing. Confirm the opening size against your harness before you put a hole saw in the firewall.

  • Nothing saws through insulation - a machined pass-through instead of a bare sheet metal edge working against your harness.
  • Two pieces; clamped - the halves sandwich the firewall so the adapter cannot walk loose with vibration.
  • Billet takes the heat - aluminum under the hood does not soften; sag or perish the way a rubber grommet does.
  • Matches the rest of the firewall - cut to sit alongside the FFG H-Pipe Bulkhead Adapter Kit.
  • The finish you appreciate later - machined or Cerakote; both still look deliberate years in.
