Super Turbo Exhausts, High Heat Spark Plugs and Cooling Upgrades

HKS manufactures a legendary lineup of performance modifications designed to maximize engine efficiency and thermal management:

Performance Exhaust Systems: From the aggressive Hi-Power Spec L II to the refined Legamax Premium and Super Turbo Muffler series, HKS exhausts are crafted from high grade SUS304 stainless steel with optional lightweight titanium tips. Engineered with smooth mandrel bends and high flow silencer designs, they drastically reduce exhaust backpressure while unleashing a deep, unmistakable exhaust note.

Super Fire Racing Spark Plugs: Modern turbocharged engines generate extreme combustion chamber heat. HKS Super Fire iridium and platinum alloy spark plugs feature specialized heat ranges designed to prevent pre-ignition detonation, cure high RPM misfires, and deliver a clean, powerful spark under intense cylinder pressures.

Intercoolers and Aluminum Boost Pipe Kits: Upgrading to an HKS intercooler kit provides a massive increase in core volume and frontal surface area. Paired with smooth bore aluminum charge pipes, these cooling upgrades drastically reduce intake air temperatures, completely eliminating heat soak and ensuring consistent horsepower output lap after lap.

Legendary JDM Performance & KDM Engineering

HKS hardware is the ultimate badge of honor across the Japanese tuning scene. Their exhaust systems, cooling kits, and ignition components are developed for the most capable performance platforms on the road, including the Nissan GT-R R35 running the twin turbo VR38DETT, the Toyota A90 GR Supra with the B58 engine, the FA20 powered ZN6 GT86, the FA24 ZN8 GR86, and the K20C1 powered Honda Civic Type R FK8 and FL5. HKS also offers specialized forced induction and cooling setups for the all wheel drive Toyota GR Yaris equipped with the G16E-GTS three cylinder turbo engine.

In addition to their iconic JDM catalog, HKS has expanded their engineering expertise into the Korean domestic market (KDM). They supply high heat spark plugs, performance blow off valves, and charge cooling hardware tailored specifically for Hyundai N models, providing critical reliability upgrades for the 1.6 T-GDi engine in the i20N and the 2.0 T-GDi in the i30N.
