Pacific Performance Engineering Heat/Sound Firewall Insulators

Diesel engines produce a lot of heat, especially in high-output situations like towing, racing, and light-to-light driving. Upgrade your tattered, dirty firewall insulation with PPE Insulator Firewalls. Pacific Performance Engineering firewall insulators create a barrier between you and the engine, reducing heat and noise entering the cab. Each firewall insulator features a ceramic fiber interior sandwiched between a tightly woven silicone fiberglass outer fabric and a woven silica inner panel finished with merrowed stainless steel wire edging and grommets for long-lasting performance and an OEM fit. They can be installed without removing the engine and provide temperature resistance up to 1,290 degrees. Show Less
