Spec: -Fuel pressure adjustment range: 196-588kPa (flow volume 40L/h, 2 to 6kgf/cm2) -Diaphragm diameter: φ36.5 -Operating temperatures: -30 to 120 。C -Pressure slope: 157x10kPa/L/h -Anti-vibration resistance: 250m/sec Fuel line connection - IN/ Direct connection with fuel line, O-ring seal - OUT/ Rubber hose connection Connector part no. - Not required Attachment method - Direct connection with fuel line, O-ring seal Features: Based on originally equipped light & small regulator, fuel pressure adjustment function is added. Adjustment range and relief ability is equal to that of standard regular sized type. By controlling fuel pressure, the most suitable setting can be made for the injector to deliver the best jetting performance. Warning: Resetting to match the engine control unit will be required.

Spec: -Collector volume: 4.1 liter (stock = 3.4 liter) -Intake pipe length: 73.8mm (stock = 48.5mm) -Intake pipe diameter: tapered from 43mm to 45mm (stock=45mm) -Material, production method: cast aluminum Features: To find the most suitable shape for tuning engines (400ps to 600ps), the diameter and the length of the intake pipe, and the cross section shape of the intake collector was redesigned. The distribution of air to each tube was improved to provide more equal airflow volume, improving torque in the mid-speed range. Improved air intake volume between the pipes of the front and rear sides reduces the difference in air intake temperature on both sides of the turbine, optimizing the air-fuel ratio and ignition timing and providing increased output and fuel consumption. Simple bolt-on installation means that no additional work is required (however, the throttle linkage and throttle sensor must be adjusted). *Intake temperature difference at the entrance of turbo chargers is improved averaging18% in 2,400 to 7,600 rpm range. *At 4,800 to 7,600 rpm, power output is increased by an average of 1.8%, while fuel economy is improved averaging 0.4%. Warning: -This product cannot be installed with the engine mounted. -Installation of this product will change the characteristics of the engine, necessitating adjustment of the engine control unit. Failure to do so very likely will result in damage to the engine. -The engine improvement figures shown above are based on internal company testing. The actual level of improvement will depend on the engine specifications, conditions of air-fuel mixture and ignition timing, weather and the precision of measurement. -This product cannot be used with single, large-diameter throttle chambers.

Plug shape: Long reach type. Thermal values, heat rate- #6 or #7. The price is for a set of 2 with resistor. * Cannot be used on direct fuel injection engines, including QR20DD, QR25DD, VQ25DD, VQ30DD, VK45DD. Spec: -Electrode material・・・・・iridium -Electrode diameter ・・・・φ0.6 -Two spark plugs per set Features: The use of iridium alloy dramatically increases ignition performance, creating much more complete combustion and increasing both increased power and response. It helps to draw out the full potential of the engine. The thermo edge set at the top of the insulator controls the deposition of carbon, which otherwise can reduce firing performance and cause poor idling. This also increases reliability and durability. Selection of heat values: Plugs with high heat ranges do not indicate higher speeds. Depending on the type of racing, the use of a too-high heat range may result in the plug not firing correctly, resulting in reduced RPM; use of too low a heat range can result in burning, causing poor high-rotational pickup. Be sure to select the plug that meets the type of racing and the engine.
