The HKS Hi-Flow Surge Tank Full Kit for the R35 Nissan GT-R is designed to improve intake balance and help keep the engine bay cooler for more stable, consistent power output. It also includes a fuel delivery pipe for adding secondary injectors, supporting the fuel system demands of high-power tuning.

HKS Hi-Flow Surge Tank Full Kit for R35 Nissan GT-R

The HKS Hi-Flow Surge Tank Full Kit for the R35 Nissan GT-R is engineered to enhance intake efficiency while helping keep the engine bay cooler for improved overall performance. Developed through flow testing on each cylinder, the design is optimized to reduce cylinder-to-cylinder variability, promoting a more stable and consistent power output. Along with functional gains, the surge tank delivers a cleaner, cooler-looking engine bay presentation. The kit also includes a fuel delivery pipe to support additional injector setup, a key requirement for fuel system upgrades when pursuing high-power tuning.

HKS Original Material and Design

• Designed and manufactured using a one-by-one molding process, the HKS surge tank is engineered for extreme power applications without compromising stock efficiency. Developed specifically for GT1000 models, it features a larger port diameter along with optimized port and cylinder designs to support high-output tuning demands. The tank dimensions are carefully calculated to deliver quick, smooth throttle response, emphasizing overall performance balance rather than peak power alone. A funnel-shaped port design on the tank side further enhances airflow efficiency, ensuring stable air delivery and consistent performance across the entire operating range.

Twin injectors

• The Twin Injector Pro Kit full kit set is designed to support high-power tuning by allowing the installation of an upgraded fuel system tailored to increased performance demands. The secondary injector side can be configured with injectors sized to meet specific power goals, providing flexibility for a wide range of tuning applications. Featuring an attachment-type design, the kit enables straightforward integration, with the standard attachment engineered to accommodate factory injectors for seamless compatibility.

Easy to install

• The layout is designed to retain factory components, including provisions for the air temperature sensor, nipples, blow-by pipe, and the left-to-right balancing pipe, allowing for straightforward installation. This design eliminates the need for custom piping or complex modifications, making fitment simple and efficient.
