Supertech BMW B48/B58 Sodium Filled Inconel Exhaust Valves - Single Groove (Set of 12)
$760.80 $950.73
$760.80 $950.73

Designed for the extreme thermal demands of high-performance and forced induction BMW B48 and B58 engines, these Supertech exhaust valves provide the heat resistance and cooling capacity required for reliable power. Each valve is manufactured from Inconel, a nickel-chromium-based superalloy that maintains structural integrity at temperatures where standard stainless steel would fail.

  • Sodium Filled: Internal sodium cavities melt at high temperatures, physically carrying heat away from the valve head and through the stem to the guides for superior cooling.
  • Inconel Construction: High-nickel alloy specifically chosen for the exhaust side to prevent deformation or melting under heavy boost or lean conditions.
  • Single Groove: Designed for use with single-groove valve keepers (collets) to provide more secure clamping at high RPM.
  • MPN: MCEVI-1400S-HS-12

This is a complete set of 12 exhaust valves, engineered to replace worn or under-performing OE units in performance-built BMW B48 and B58 cylinder heads.
