• HKS changed the gasket material from paper to metal with NBR coating on a side of
  cold-rolled steel sheet. These won’t stick like the stock ones when replacing the intake manifold.
• Metal+Bead type. Ensure the sealing performance at high temperature and high boost.
• Metal material keeps rigidity of surrounding intake air parts even after changing or
  replacing surge tanks etc.
• Engraved with HKS logo.
