HKS Intercooler Pipe Upgrade kits, by design, increase the efficiency and performance over the factory intercooler pipe system. The application specific kits utilize mandrel bent metal pipes to replace the restrictive factory rubber or plastic intercooler pipes, which have the tendency to expand, come loose, or crank under boost conditions or due to deterioration. The use of the metal intercooler piping offers increased durability, consistent boost pressure, and an attractive appearance. Steady and/or higher boost pressure and improved response are typical gains from just installing the HKS intercooler pipe upgrade kits alone. Each HKS kit is designed to seamlessly integrate with the factory turbo and intercooler systems with the included aluminum or steel pipes, silicone hoses, stainless steel clamps, and other applicable hardware. Some applications offer polished aluminum piping and can be used with HKS intercooler upgrade kits.
