Cold air means more power. The best way to take advantage of this principal in your Honda Civic is to upgrade your intercooler and charge piping with these kits from HKS. Intercooler and Charge piping upgrade kits by HKS are designed for each individual application and use piping diameters and intercooler cores that are sized specifically for each vehicle. Unlike other manufactures who simply fit the same intercooler to every kit HKS calculates the correct airflow needed to prevent boost loss across the intercooler while still providing good cooling, even under race conditions. Larger and smoother than OEM piping allows for better airflow, increased throttle response, and decreased turbo lag. Each HKS kit comes with all required hardware, fittings, brackets, and silicone couplers for simple bolt in installation.
