Heat management is absolutely critical for the 2.4-litre FA24 boxer engine, especially when subjected to sustained high-rpm track driving or heavy fast-road use. High oil temperatures can rapidly degrade lubrication and cause catastrophic engine failure. Keep your engine completely stable under extreme circuit loads with dedicated Oil Coolers, ensuring your GR86 performs consistently lap after lap. To maximize coolant efficiency and prevent overheating on hot track days, upgrade your factory plastic-tanked unit to high-capacity aluminium performance Radiators.
