4ValveCylinder head for high revolutions & high power!
The one and only 4ValveCylinder head for explosive acceleration that you can't experience with a normal cylinder head.
4ValveCylinder head
Intake efficiency is improved in the large range by making it 4Valve..
Spark plug is placed in the center and the shape of the combustion chamber is changed to optimize combustion efficiency..
Air intake port
In order to improve the intake efficiency, the intake ports have been enlarged and an oval shape has been adopted..
Dedicated Manifold
The manifold shape is also oval to optimize the flow from the throttle body to the intake port..
Large Capacity Injector
Proper combustion is possible by replacing the injector with one that has a larger discharge capacity to match the increased intake air volume due to the 4VHead design..
Combustion setting is possible by using the special MAP with the injection controller (sold separately)..
Aluminum Forged Piston
Extensively designed Piston for 4V.
By cutting from a special forging material, we were able to achieve a high compression ratio of 12.5 while maintaining a lightness that cannot be achieved by cutting out the universal forging material and a strength that can withstand the high output of 4V..
Aluminum forged roller rocker arm
A roller is used for the contact surface of the camshaft to reduce frictional resistance and to increase output..
The Locker Arm itself is produced by forging aluminum to achieve both lightness and strength, which helps to increase power..
Tappet clearance adjustment is the same way as for NORMAL.
