BMW E82 135i Cooling System Refresh Kit

Reliably controlling engine temperatures is critical to engine longevity and performance. In fact, most engine mechanical and electrical systems rely very heavily on strict temperature boundaries to function at all.

ECS recognized the educated BMW owner's need for a single service kit to address the most important engine cooling components. The Level 1 Cooling System Refresh Kit accomplishes this goal; an engine thermostat, water pump with hardware, coolant inlet and outlet hoses, & one gallon of BMW coolant are all included - giving you superior control over power-robbing heat.
