Description: Mazda 6i enthusiasts are very familiar with a loss of spark advance and
sluggish performance when the 2.3L engine heats up. This device monitors the engine head
temperature and activates the Mazda6 cooling fans at a much lower temperature (180°F) to improve
engine cooling and preserve the spark advance timing for a more responsive throttle. Simple
one bolt, one wire installation! For more details on this device please

Updated 2008 Design * Universal Adjustable Fan Controller (For Mazda6s and Mazda6i)
Use with Thermal Sensors shown below.
Description: Mazda6 enthusiasts are very familiar with a loss of spark advance and
sluggish performance when their engine heats up. This device directly monitors engine temperatures using a coolant or block thermal sensor and
activates a radiator cooling fan at temperatures as low as 160F. Activating the fans sooner reduces the engine coolant temperature
to preserve the spark advance timing for a more responsive throttle. This unit is fully adjustable and can be adjusted out of operation
for winter driving conditions. Order with either the 'Engine Block' or 'Coolant' thermal sensors described below. The installation kit includes
all parts and instructions for both Mazda6s and Mazda6i vehicles. Price: $45 Sold Out $5 off on Combo Deal with Coolant or Block Sensor!!
(See order form.)
