The PPE 149000124 Firewall Insulator � Gold from XDP replaces the damaged firewall insulation on your 2001-2005 GM 6.6L Duramax LB7/LLY. Diesel engines produce a lot of heat, especially in high-output situations like towing, racing, and light-to-light driving, which can cause the factory insulation to deteriorate over time. Create a barrier between you and the heat on your 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 OE-style 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 create a temperature resistance up to 1,290 degrees.
Features:
- OE-Style Fitment
- Ceramic Fiber Interior
- Merrowed Stainless Steel Wire Edging
- Can Be Installed Without Removing Engine
