Defi
Water Temp Meter/Alfit Adapter
Using an aftermarket water temp meter can help accurately monitor your engine's cooling system, as factory temperature gauges offer limited information when problems occur. The Defi Link Meter uses accurate stepping motor technology to provide precise readings, while the optional Alfit sensor adapter makes installation simple.
High Pressure Radiator Cap
Using a high-pressure radiator cap in conjunction with aftermarket radiators can aid in your vehicle's cooling system by causing the coolant's boiling point to rise, increasing cooling efficiency. A number of companies offer caps with various pressures, such as this Koyo high pressure radiator cap, rated at 1.3 bar (kg/cm2) or 18.5 psi.
