High recovery material allows header or manifold flange to stay sealed if flange loses clamp-load. • Can be trimmed if necessary for modified port applications. • For OE replacement, high performance street, drag race and oval track use.

  • Has A Graphite Core W/ Steel Outer Layers
  • Graphite Core Has Excellent Thermo-conductivity
