    very well made. easy to install

    I have owned this 1980 Porsche 911 Weissach for 35 years so am very familiar with every aspect of the vehicle…live in Florida where, even in late model vehicles, A/C systems are almost always inadequate. The 1980 911 was never made for comfort, specifically cool cruising in hot humid weather. I chose the Griffiths evap core for several reasons. First, it was designed and manufactured specifically as an “upgrade” for 911 cars. And second, because an evaporator replacement procedure is not anything one wants to do twice to the same car. I trusted Griffiths and purchased their evap kit, which also included their filter/dryer. I performed the replacement exactly to the letter of the 6-page instructions that Griffiths provided. I had a few questions and called the company where my questions were quickly answered by their representative. I can state that categorically, Griffiths parts are high quality…and fitment superb. Also, this kit came with new hose adapters and seals enduring no leaks.
    I have photos of every step taken and a center A/V outlet vent temperature below 34 degrees F! Way cool.

    My factory evaporator was leaking and this aftermarket upgrade was recommended in several forums. Installed it and new barrier hoses using the great step by step instructions provided and I have had cold air ever since (about 2 years).

  13. Tony Stefanik

    This evaporator can really beat the Mississippi heat. Thanks for the excellent customer support as usual.

  14. James Ayers

    Being cool is where its at. Top notch quality and it fits great.

  15. Frederick S.

    Installation easy, good instructions, Blows 53 at middle point on Thermostat and 39 at lowest setting which I only left it there for a moment not wanting to freeze up the Evaporator. A ambient temperature and HI/LO pressure. chart would be good for both R12/R134

    Great product that seems to work well. The only issue I have is that the extra parts and the instructions were all for a left hand drive. Had to work out how to get to the evaporator and remove it in a RHD car which is completely different.

    • Griff

      Well noted. We do have some RHD instructions which should have been included. Sorry you did not reach out to us and ask.

  22. Jim Sutherland

  23. Frank M.
