"High-dimensional Super Turbo Muffler Debut" Exhaust Efficiency & Sound Pressure Reduction are implemented together. The turbo engine master HKS challenged to implement the following 3 characteristics together to develop Super Turbo Muffler. Effective on stock to high performanceA vehicles w/ upgraded turbines. The performance exhaust sound meets the JASMA standard. Unique exhaust sound designed specifically for the engine.

High quality sound. Sport exhaust system with reduced noise level. In addition to high performance and sporty appearance, Silent Hi-Power muffler reduces noise level, making it the best choice for more mature enthusiasts. The Silent Hi-Power mufflers are made of SUS304 grade stainless steel for high lustre and durability. HKS has introduced a "Silent Chamber" for specific applications. The Silent Chamber works to reflect sound waves created by engine to cancel each other out. This closed-end structure creates a high muffling effect with almost no effect on performance.

The real street sports muffler. Hi-Power 409 mufflers offer a cost effective solution for your sports muffler needs. The rear section is made from SUS304 grade stainless steel for a high lustre finish and the piping section which is not visible once fitted is made from coated SUH 409, reducing the cost. SUH409 has other benefits such as being more resistant to thermal expansion and improved acoustic properties. SUH409 has the ability to absorb more sound than SUS304 which allows Hi-Power 409 mufflers to have a straight through design without fear of excessive noise.

For further performance enhancement. Universal sport type catalytic converter that can be used various level of tuning cars. It is well balanced for high horsepower and high cleaning performance. Target Horsepower 500 - 600PS. It is well balanced for high horsepower and high cleaning performance. Oval and Round types are released for various vehicles. Oval Type can be used for D85 - D90 and Round Type can be used for D115. (Modification is required.) As they are universal type, flanges need to be welded.

STAINLESS STEEL HIGH PERFORMANCE FRONT PIPE. Front Pipe decreases secondary exhaust gas pressure of turbine to improve response. Stainless steel is durable and good looking. Flanges are also made of stainless steel and tig welded that reduces exhaust gas friction.

A stock extension is designed to merge the main port (turbine exhaust) and bypass port (wastegate actuator) in turbine exhaust housing. This causes the exhaust stream from the main port to interfere with the bypass port stream when the actuator is opened. The primary and secondary exhaust pressure will rise causing the boost pressure to drop, which can cause a loss in power. The HKS Extension Kit will optimize the turbines performance with minimal power loss.

The fun to drive at will and the balance can be adapted from circuit to winding roads Raised Driving-Comfort, ❝Ultimate All-Round❞

To pursue a comfortable ride and more enjoyable handling performance.

Return of Drag Specification Dampers Introducing the latest technologies to suit modern drag racing requirements The drag suspension designed based on HIPERMAX II Drag Suspension. Parts such 300mm long spring, helper spring, etc. are selected for each vehicle model to maintain sufficient stroke amount and traction. The shock-body length adjustable type is chosen to widen the vehicle height setting range and stroke distribution. This drag suspension guarantees its performance in drag race.

～Obsession with High Quality～ Integration of quality over cost principles of tuning parts and benefits and compatibility gained from OEM design. Unlike most stock fitment type suspension kits, premium "ride comfort," "style," and "stability" are pursued at the highest level and realized by HKS in this product.

The most powerful intake system carefully designed to fit engine room of a vehicle. HKS Racing Suction pushes air intake system efficiency to the limits.

Filter of Super Power Flow collects dust and intake efficiency will decrease after long time usage. In order to keep dust collection and engine performance, filter should be periodically replaced.

Air flow meter is one of big suction resistance. It can be removed as D-Jetro and controlled with "F-CON V Pro". Performance is greatly improved when Racing Suction Reloaded is also installed. With "Air Flow Less Adapter", air flow meter can be easily removed. Buffing finished aluminum cast pipe can be replaced with air flow meter. There is a boss on the pipe to install intake air temperature sensor (Modification is required).

HKS Super SQV (Sequential Blow Off Valve) uses a unique sequential valve structure and a differential pressure control system, which allows for a broad operating range from low boost to high boost. Its Pull-Type relief design ensures stable operation regardless of the amount of boost pressure. The Super SQV will support new generations of turbocharged vehicles.

Get the Turbine's Real Power and Increase Engine Torque! All HKS Intercoolers improve both the efficiency and power of any turbocharged application by rapidly reducing inherent heat levels of the compressed intake air charge before entering the engine. By utilizing a special tube and fin design, the intercooler acts as a large heat exchanger that dissipates the heat generated by the compression of the intake charge without creating reductions in boost pressure or response.

HKS PIPNG KIT for Durability Increase and Consistent Boost Pressure under High Boost Condition. Stock plastic or rubber intercooler pipes can expand or crack under high boost levels. In addition to this, stock pipes have many bends which in some places are very tight radius which causes much resistance and pressure drop. HKS Piping kits are made of aluminum for increased durability and safety. The pipes have been redesigned to decrease the number of bends and to increase bend radius to minimize pressure loss and flow resistance.

Two types of kits are available with R Type kits: filter relocation type and S Type: sandwich type which is held at the oil filter. Oil Temperature Controlled by Thermostat HKS Oil Coolers use high performance cooling cores; so there is the possibility of overcooling which is prevented by the use of a thermostat (some vehicles excluded). This thermostat has high response and able to react quickly to change of oil temperature. Once oil temperature reaches the set level, the oil will flow through the cooler core but bypasses when temperatures drop lower. This allows engine oil to be maintained at the ideal temperature. * Thermostat Opening Temperature 70 (±3) * Thermostat Full Open Temperature 80 (±3) Thermostat relief feature allows for safe operation in times of emergency In cases where the core or lines become blocked and the oil pressure rises, the thermostat will bypass the core to maintain the correct oil pressure and prevent damage to the oil lines and fittings Stainless braided hoses chosen for increasing durability Hose lengths and fitting types are tailored to each vehicle application to ensure easy and tidy fitting while preventing connection errors.

Newly designed case shape improves durability and oil flow amount. HKS Oil Pump Upgrade provides reliable oil supply for tuned engines.

Setting the injection-valve opening pressure to 1.1kgf/cm2, and using silicone rubber as a packing part can improve sealing properties. This radiator cap can support the reliable cooling performance under severe driving conditions.

The Pursuit of Maximum Camshaft Efficiency The concept behind the HKS camshafts was to produce something that the customers would be truly happy with. This sounds simple on the surface but this is something very challenging. When the development team looked carefully at the details, the ultimate conclusion they drew was to look at the core purpose of the cam itself (to smoothly allow air into and out of the combustion chamber) and a good cam would do this job for the maximum efficiency.

Cam feeling correction for a variety of engine and use.

Valve Spring for High RPM Engines Valve spring performance is very important for valves to follow accurate cam profile.

The Performance requirement from Head Gasket. As the cylinder block and head are not rigid body, when the Head Bolts are tightened, the gap between the surfaces and the surface pressure applied is not even across the whole surface. Moreover, due to combustion pressure and vibration while driving, the conditions are continually changing and the contact surface is being continually beaten. As a result, a good gasket must ensure that contact surface pressure is spread as evenly as possible and also adapt quickly to the ever changing gaps that can appear in the contact surface to maintain a good seal with good pressure.

For drivers who just need "more power and more torque", HKS have designed a series of capacity upgrade kits to suit each engines characteristics. Increased displacement offers more torque at lower engine speeds and by using the highest quality materials, the durability required for high levels of tuning is achieved. Nickel coated pistons which have strong anti-knocking properties combined with fully counterweighted crankshafts and high strength connecting rods (rods optional in some kits) combine to extract maximum performance from the turbocharger and increase torque.

Forged Piston Kit has been designed to provide a durability when upgrading your engine. Forged piston target clearances are different for each engine. Please check the instruction manual or contact your dealer for details.

The tuning expert HKS provides the clutch system for streets and sports use. Capable torque, pedal effort, and semi-engagement range are closely examined for various driving situations. Despite the support of approximately 700ps, the main concept for the Twin Plate LA Clutch remains the same. Using "MG Composite Discs" to reduce judder and achieve better driving feel compare to stock clutch. Disc dampers are used to reduce gear noise and protect the transmission from shock torque. The LA Twin also has a "Pivot Ring" within the pressure plate to offer partial engagement like no other twin plate clutch.
