Separated tank type High-flow Surge Tank Kit was developed for R35 GT-R that enhances the appearance in the engine room. By the flow test of each cylinder, HKS has designed it to eliminate the variability between cylinders, which produces more stable power output. HKS Surge Tank improves its appearance, too. HKS Surge Tank Pro Kit includes Delivery Pipe for additional injector installation, which is necessary for high-power tuning.
