Don't let the heat of your engine make you sweat With Heatshield Products Header Armor, underhood temperatures can be reduced by up to 60 percent, keeping your vehicle cool at the track or on the street. Wrapping headers with Header Armor keeps heat in the exhaust system and out of the engine compartment. This lowers underhood temperatures, helping with overall engine cooling and with less heat being transferred to the passenger compartment through the firewall. Header Armor also results in hotter and faster-flowing exhaust gases, which creates a scavenging effect to pull intake gases through the system quicker. This lowers intake temperatures, resulting in more power. The abrasion-resistant Header Armor material cuts effortlessly with heavy-duty scissors, making it simple to install. It wraps around header pipes of small or large diameters, and removal of the headers is not necessary for installation on many vehicles. This product is made of high-quality materials to serve you for years to come. It will meet your needs and deliver great quality at an affordable cost.
