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.

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.

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.

Comes with stabilizer link pair + 25mm bush.

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.
