ACUITY REPLACEMENT TPS & MAP PLUG - K-SERIES COOLANT HOSES showed an 8-9 horsepower peakWhile investigating the overheating issue that affects FK8's in hot conditions, ACUiTY engineers determined that the radiator can reject more heat if the water flow through it is reversed. This is due to how the intercooler rejects heat from charge air and how that heat flows through the lower part of the radiator. In very hot conditions on cars that also have upgrades like hood venting and an upgraded radiator, water temps were reduced by as much as
