Types of HKS

HKS is a brand that specializes in performance parts for vehicles, mainly used for tuning and modification to enhance performance, handling, and overall driving experience. Below are some types of HKS products found in the market:

  • HKS intercooler: The intercooler is a crucial component in many performance vehicles. It cools the compressed air coming from the turbocharger before it enters the engine. By cooling the air, the HKS intercooler increases the density of the air, allowing the engine to extract more power from the forced induction. As a result, the vehicle experiences an increase in horsepower and torque. Besides, the cooled air has a lower temperature, which reduces the risk of engine knock. HKS intercoolers are available in different types, including front-mounted, top-mounted, and tube-and-fin designs.
  • HKS exhaust manifold: The exhaust manifold collects exhaust gases from the engine cylinders and channels them into the exhaust pipe. By doing this, the HKS exhaust manifold helps reduce emissions from the vehicle. Different types of HKS exhaust manifolds are available, including log, header, and ram's horn manifolds. Each type is designed to improve airflow and reduce exhaust back pressure, contributing to better engine performance.
  • HKS turbo: The turbocharger forces more air into the engine, which allows combustion of more fuel, resulting in more power. As a forced induction component, the HKS turbo increases the horsepower and torque of the vehicle. The increased power output is beneficial for acceleration and overall driving performance. By compressing the intake air, the HKS turbo raises the intake air pressure and temperature. This process leads to better throttle response and ensures the engine has more air ready for combustion with every pedal push.
  • HKS coilovers: Coilovers combine the shock absorbers and the springs into a single unit. They replace the factory-installed suspension on vehicles. The HKS coilovers allow users to adjust the ride height of the vehicle according to their preference. Besides, they improve handling by lowering the center of gravity. With the coilovers fitted, the vehicle experiences a reduced body roll, ensuring drivers and passengers feel the car respond to steering commands. The coilover also comes with adjustable damping forces.
  • HKS supercharger: The supercharger is a component fitted into the engine to increase power output. It is similar to the turbocharger, as it forces more air into the cylinders. However, the HKS supercharger draws its power from the engine's crankshaft. By pushing more air into the cylinders, the supercharger allows the engine to burn more fuel. This process leads to a significant increase in horsepower and torque.
