Intercooler Kit (13001-AN015) by HKS®. GT1000 2 Core Front Mount. Components: Intercooler core assy (2). Intercooler inlet pipe. Silicon hoseThe intercooler is very important for forced induction tuning and HKS has developed new big type for GT1000 full turbine kit. HKS has designed the intercooler for best balance of left-right bank cooling and pipe layout for the same as vertical flow stock design. The core front surface is maximum size as stock type layout. And the thickness of core is 100mm (stock=65mm) which provides less air flow pressure loss for the 1000ps. HKS has designed the intercooler layout design to be installed with the stock air guide (need some work). The air came in from the open bumper is all flowed into the core for the maximum cooling efficiency.
