This camshaft is designed to maximize power output under the ECU rpm limiter in order to achieve a more suitable power curve characteristic for the S MAX engine. The profile is especially designed to work well with the KOSO Φ63 High Performance big bore Kit. The base circle has been designed with a smaller diameter to reduce friction loss and to minimize valve jump.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
Valve clearance must be adjusted at the lower limit of the OEM value or a tappet sound occurs. 。 At first, when I adjusted it at the middle position, the tappet sound was bothering me, but after that, when I adjusted it at the lower limit, the level became almost not bothering me.View Detail
