Review GRIMMSPEED Phenolic Thermal Manifold Spacer 3mm 02-14 Ej fits WRX STI 2004–2021

Introducing the Grimmspeed 018001 Phenolic Thermal Manifold Spacer for Subaru WRX and STI models from 2002 to 2014 (for EJ engines) and 2004 to 2021. This high-performance component is designed to enhance the cooling system in your Subaru, ensuring optimal engine temperature and improved overall performance.

The Grimmspeed Thermal Manifold Spacer is meticulously crafted from phenolic material, known for its exceptional thermal conductivity and resistance to both heat and engine coolant. This material is ideal for use in high-performance applications, as it helps to dissipate heat more efficiently than traditional materials like aluminum or steel.

The 3mm thickness of this spacer provides an increased gap between the engine block and the coolant manifold, allowing for better airflow and cooling efficiency. This results in more consistent engine temperatures, which in turn can lead to improved power output and increased fuel efficiency.

The Grimmspeed Thermal Manifold Spacer is a direct replacement for the factory component, making installation straightforward and hassle-free. It is designed to work seamlessly with your existing cooling system, ensuring that all components function together effectively.

The phenolic material used in the Grimmspeed Thermal Manifold Spacer is also resistant to warping or distortion, even under the most demanding conditions. This means that you can trust this component to maintain its shape and function optimally, even after extended use.

In summary, the Grimmspeed 018001 Phenolic Thermal Manifold Spacer is an essential upgrade for any Subaru WRX or STI owner looking to maximize their engine's cooling efficiency and overall performance. Its high-quality construction, superior thermal conductivity, and resistance to heat and coolant make it an excellent choice for those seeking top-tier results from their vehicle.
