A 4-cylinder engine has a fatal secondary vibration whose crankshaft generates two vertical vibration by one rotation. This mainly becomes the serious obstacle of inertia, such as a piston, raising rotation of engine owing to. Although the crank cap corresponded to high rotation and the high output with the ladder beam over No.2, No.3, and No.4, by spoon, B18C investigated high rotation and the high output further, and was taken as the design which unified the whole block lower part. For K20A.
Material: Aluminum. Piston size: 40.46φ + 36.12φ. With braket and bolts. DC2, DB8, EK9 and CL7 need to equip to Brake Rotor(030-275-001) . 4 POTS. Price for front pair. Standard (1) is 4.7kg but MONOCOQUE CALIPER (1) is 2.6kg. The actual contents may vary from the one shown in the picture depending on the selection. Please choose the model from:
Parts number:
45020-MBR-G00 Reverse For AP1/2 or EP3
45020-MBR-G01 Reverse For DC5
45020-MBF-G01 Forward For DC2, DB8 or EK9
45020-MBF-G00 Forward For CL7 or ZF1/ ZF2
This thermo stat would open the valve in 70 degrees in order to avoid power down of the over heating. Original thermo stat would open the valve in 90 degrees. K20 engine has some problem for heating emission, this product keep the water temperature about 70-75degrees.
For FD2: Center pipe: 65mm, Tail pipe: 75mm, Weight: 4.5kg (OEM7.2kg), 90db. Made by SUS. Please choose the model:
Parts number:

18030-EP3-011 for EP3
18030-FD2-011 for FD2
The intake part of this throttle size is 4mm larger than that of original so intake efficiency is 17% up of the original. Butterfly size is 2mm bigger than the original this makes intake efficiency 8% up as well. Interior of the body part is polished by diamonds and mirror worked. This product is electronic. DO NOT install it with a wired accelerator. Makes about 2mm space if you install this to FN2 stock intake manifold so it's better to use with Spoon Sports intake manifold
The spoon formed the silencer in a part for the central part of Exhaust Pipe-B. Moreover, the optimum exhaust flux was designed and produced commercially.
Parts number:
18220-DC2-001 for DC2 Type'96,DC2 TypeR'98(B18C engine)
18220-DC5-001 for EP3, DC5(K20A engine)
18220-EK9-001 for EK4, EK9(B16A, B16B engine)
18220-GDA-002 for GD1, GD3, GD3 1.5S(L13A, L15A engine)
18220-FD2-001 for FD2(K20A)
By using numerical control machining to achieve a large, 4mm opening for the throttle, the flow-pass area is increased by 16% and the inertial mass during the intake of air is reduced. Accordingly, peak power is increased by a factor of approximately 6 horsepower.
Parts number:

16400-AP1-040 for AP1-100, AP1-110, AP1-120, AP1-130, AP1-135, AP1-200 (F20C engine)
16400-AP2-020 for AP2-100, AP2-110 (F22C engine)
16400-DC5-020 for EP3, DC5 (K20A engine)
2 layer all aluminum. It can use with stock air conditioner. Comes with Spoon radiator cap. Exact same style as OEM radiator but core pressure is 35mm (OEM 10mm) so cooling effect is abou40% up. Show use with Spoon thermo switch and thermostat. Please also use with SEP radiator hose. Please choose the model. Shown photo is for EK9.
