●Skut Piston
The piston skirt of the aluminum cast piston is molybdenum coated to improve initial break-in.
●N-20 Camshaft included
Optimal profile that maximizes the performance of the normal cylinder head improves output performance.
Includes an automatic decompression mechanism similar to the normal one.
●FI Con TYPE-X (injection controller)
When installing SP Takegawa bore up kits or muffler parts, the air-fuel ratio will deviate significantly from the ideal, so it is necessary to correct the fuel injection time with the FI Con.
It can be installed by simply disconnecting the coupler of the genuine ECU and connecting it.
The FI Con TYPE-X has multiple data settings pre-configured by SP Takegawa to match SP Takegawa engine parts, so you can easily select, change, and correct setting data using a PC or smartphone according to your engine specifications.
The injection time can be adjusted up to a maximum increase of 5000μs and a maximum decrease of 7500μs, making it widely applicable from normal displacement to bore up vehicles.
It also has a monitoring function for engine RPM, engine temperature, throttle opening, and injector opening/closing rate using a PC or smartphone, making it very convenient for setting.

Newly designed SP Takegawa original big throttle body kit (φ34)
This big throttle body kit is for vehicles equipped with an SP Takegawa sport camshaft or S-Stage bore up kit, along with an SP Takegawa FI Con TYPE-X (injection controller).
By installing it, you can achieve improved output performance in the high RPM range and engine characteristics that rev smoothly, which are not available with the normal throttle body specifications.
●Air filter for big throttle body (with blow-by union) included
●SP Takegawa original inlet pipe (for normal cylinder head) included
