CSOhara Coolant Breather Heating Waterway Deleting Kit is designed to change and divert the antifreeze heater waterway for reducing intake air temperature by suppressing surge tank temperature rise, promoting radiator efficiency by reducing cavitation air, and countermeasures against knocking by reducing heat accumulation in the first cylinder.

CSOhara Intake Manifold Insulation Gasket Kit is designed to block heat conduction, lower intake air temperature, and increase oxygen density. This is an insulating gasket that suppresses the temperature rise of the intake manifold due to engine heat. As the intake air temperature decreases, you can expect an increase in power due to the increase in oxygen density.

A must-have item for the AP1 drive-by-cable engine. CSOhara IAT Sensor Insulation Gasket Kit is an insulating gasket that blocks secondary rise in the intake air temperature sensor body due to surge tank heat. Since the intake air temperature value decreased after installation, it can be confirmed that the ECU was recognizing a value higher than the original intake air temperature due to the influence of heat damage.
