The AVT Liquid to Air Barrel charge cooler is a world first exclusive in its design for the industry. The Radical cylindrical shape was designed for drag and street applications, providing maximum cooling, airflow and performance efficiencies. The core is one piece aluminium, and provides a true counter current water flow design for optimum cooling. Rule of thumb - Always choose the largest core you can fit / afford, regardless of your power level. A 300hp install using a larger core will have better results than a smaller core at the same power level. The power can be achieved with lower boost and more efficiency and heat soak The AVT Liquid to Air Barrel charge coolers are available as an individual unit or in "Kit Form" - We also have radiators, pumps, piping kits and header tanks.
