If you’re tired of the rate at which the OEM firewall insulation deteriorates and would like to dress up your engine bay, the PTP Firewall Barrier was designed to replace the OEM firewall insulation on the Volkswagen MK5 and MK6 GTIs in addition to the MK6 Golf R.

Designed to be a one-time fix for this deterioration problem, the PTP Firewall Barrier also provides superior thermal resistance and sound deadening over the factory insulation.

With the front layer made from actual pulverized volcanic lava rock (continuous-filament basalt) formed into fabric and woven into a tight mesh weave, these firewall blankets are internally insulated with high temperature calcium magnesium silicate wool, overlaid with a high temperature silicone fiberglass.
