Earl’s quoted specs:

Features

  • Manufactured in the U.S.A from aircraft spec aluminum alloy, using the latest vacuu= m brazing technology.
  • Corrugated screen internal turbulator plates increase both thermal efficiency and mechanical strength resulting in the most efficient, smallest and ligh= test practical package.
  • Manufactured from thin aluminum plates for the fastest possible heat transfer.
  • Inlet and outlet fittings o-ring to the top plate assembly.
  • Designed for the range of oil flows and air speeds encountered in high performa= nce automobiles.
  • Available in three widths with inlet and outlet fittings male AN.
  • Every cooler is pressure checked to 175 psi. Periodic samples are burst test= ed to 350 psi. <= o:p>
