Bilt Racing Service BRS 160F Low Temperature Thermostat MY09-12 9A1


In stock

SKU: 106-06.6

Our exclusive 160F low temperature thermostat fits Porsche Boxster, Cayman, and 911 models from 2009 through 2012.

Note: This product is intended for track use only and will cause a pending or active CEL, but will not affect driveability or cause the engine to enter limp mode.



Our 160F low temperature thermostat is not available from any other vendor and features a calibrated, German-made 160F thermostat. It is calibrated to allow thermostat opening a full 20-25F degrees earlier than the factory thermostat.

That means that the the low temperature thermostat is designed to be fully open by 180-185F, allowing for full flow to the cooling system to maximize cooling potential. With high on-track water and oil temperatures, the 9A1 engine can use every bit of cooling it 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 50,000. Please be sure to remove your bumper cover and clean out your radiators for maximum cooling benefit!

We recommend using Driven CSP (Cooling System Protector) and also fitting 9A1 engines that are tracked with a 2.5 quart deep sump for maximum engine cooling (up to a 40F oil temperature drop has been reported).
