The Header Manifold Blanket provides excellent heat retention for exhaust headers and manifolds. This flexible heat shield simply clips into place on the upper portion of the header. The fabric side of the material faces the heat source; the aluminized side faces away, offering protection from abrasion and harmful liquid spills. The Header Manifold Blanket is available in two different kits: Two 20" x 24" blankets for V-6 and V-8 applications or One 36" x 40" blanket for straight 6 & 4 cylinder engines.
