Product Details

The Supertech Performance SEAT-H1003E is a precision-machined exhaust valve spring seat designed for use with Honda D16A series engines. Spring seats provide a stable, hardened seating surface for valve springs, helping to maintain proper spring geometry and reduce wear on the cylinder head during high-performance or high-RPM operation.

Key Features:

  • Precision-machined construction for consistent fitment and reliable performance
  • Designed specifically for the exhaust side of Honda D16A series engines
  • Provides a durable interface between the valve spring and cylinder head
  • Compatible with Supertech Performance valve spring upgrades for a complete valvetrain rebuild
  • Manufactured to exacting tolerances for OEM-equivalent or better fitment

The SEAT-H1003E is an essential component when rebuilding or upgrading the valvetrain on Honda D16A-equipped vehicles, ensuring proper spring alignment and long-term durability under demanding conditions.
