The Honda Civic Type-R with K20C turbo engine achieves 320ps with 2.0L with boost pressure exceeding 150kPa. The engine intake air temperature rises to nearly 90°C showing the stock intercooler capacity is insufficient.

The HKS intercooler uses a larger size intercooler to maintain cooling performance. The newly designed 100mm wide core allows approximately 200% more area when compared to that of the stock core capacity. The stock intercooler piping layout has a sharp bend stopping the intake air flowing smoothly and causes boost pressure drop. The HKS intercooler integrates the inlet side tank of the intercooler and pipe to allow smoother air flow and reduced air intake losses.

13001-AH004 Intercooler kit includes 13002-AH001 piping kit. Replacing the stock rubber intercooler inlet and outlet hoses with aluminium piping eliminates pipe expansion that can be associated with the stock factory piping, allowing greater boost levels to be run and improving throttle response.
