A Spacer is designed to optimize the performance of your aftercooler system. An Aftercooler Spacer, also known as an intercooler spacer, is a component used in turbocharged or supercharged engines. It's typically a metal that is located between the aftercooler (or intercooler) and the engine.It prevents overheating and maintains the overall performance and efficiency of the engine. It is typically made of brass.Attributes:• Provides enhanced thermal conductivity for optimal cooling efficiency• Manufactured to precise specifications and are built for durability and reliabilityApplications:A Spacer is used to reduce the heat transfer from the engine to the aftercooler.
