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.
Please choose the model. The actual product may differ from the one shown in the image.
Parts number:
19500-DC2-000 for DC2, DB8
19500-DC5-000 for DC5, EP3
19500-EK9-000 for EK4, EK9
19500-FD2-000 for FD2
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.
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
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 product has been developped in response to considerable demand for a balance between peak power and torque. In its development, we at Spoon have implemented all possible combinations of pipe diameter, assembly rotation, and other similar factors in exhasutive engine-bench, flow-bench, and actual-driving tests. Accordingly, power and torque were successfully balanced, and by both including a bulge in the assembly-collector section and using slightly uneven lengths for pipes, it was possible to achieve our ultimate target or reduced weight. Furthermore, with any reduction in low speed torque, the discharge of gas was carried out forcibly from the exhaust port in the high speed range, and the results of this showed that ithas also been possible to achieve increased replenishment efficiency for the combustion chambers. In other words, we have been successful in the development of an exhaust manifold with a real increase power.
Please choose it for front or rear. (#45140SN0101) Front is exact same item as RIGID COLLAR 50261-BR9-000 and (#45230SN0201) Rear is excact samte item as RIGID COLLAR 50300-BR9-000
