Does anyone have experience will Earl’s “Temp-A-Cure” oil coolers with a 13B = rotary?

or

Earl’s quoted specs:

·        Manufactured in the U.S.A from aircraft spec aluminum = alloy, using the latest vacuum brazing technology.

·        Corrugated screen internal turbulator plates increase both thermal efficiency and mechanical strength resulting in the most = efficient, smallest and lightest 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 performance automobiles.

·        Available in three widths with inlet and outlet fittings = male AN.

·        Every cooler is pressure checked to 175 psi. Periodic = samples are burst tested to 350 psi.
