Description Shipping information

Diesel engines produce a lot of heat, especially in high-output situations like towing, racing, and light-to-light driving. Time to upgrade your tattered, dirty firewall insulation with the brand new PPE Insulator Firewall.

Create a barrier between you and the heat on your 1999-2007 Duramax diesel engine with this custom-fit replacement. This functional upgrade features merrowed stainless steel wire edging for long-lasting performance and grommets for an OEM fit. The ceramic fiber interior is sandwiched between the tightly woven silicone fiberglass outer fabric and the woven silica inner panel. The combination of materials and workmanship creates a temperature resistance up to 1,290 degrees.
