LN Engineering's exclusive 71 degrees celicous (160F) low temperature thermostat fits Porsche Boxster, Cayman, and 911 models from 1997 through 2008.

The factory thermostat doesn't start to even open until 86 degrees celcious (186.8F) and doesn't fully open until almost 98.8 degress celcious (210F). This causes hot spots inside your engine that can result in cracked heads and cylinder failures from overheating. LN's 71 degrees (160F) low temperature thermostat is not available from any other vendor and features a calibrated, 71 degrees (160F) thermostat. It is calibrated to allow thermostat to open much earlier than the factory thermostat.

That means that the the low temperature thermostat is designed to be fully open by 82-85 degrees (180-185F), allowing for full flow to the cooling system to maximize cooling potential. With high on-track water and oil temperatures, the M96, M97 and 9A1 engines can use every bit of cooling they can get!

The thermostat sold by LN Engineering is the only one used and recommended by Flat 6 Innovations and should be installed anytime a new Genuine Porsche water pump is installed, which should be replaced no later than 4 years or 80,000 kms (50,000 miles). Please be sure to remove your bumper cover and clean out your radiators for maximum cooling benefit!

Application note: Even if you have cleaned out your radiators, please be advised, some late-model cars do not report actual coolant temperature, so some users will not see any visible change in operating temperature when fitted with a 160F low temperature thermostat.

Replaces Porsche part numbers 996 106 125 52 (53). Does not fit GT2, GT3, or Turbo models.
