Garage Yoshida R35 Coil Diversion Kit

The engine output of the R35 is naturally higher than that of the RB26, and the air-fuel ratio is also thinner than that of the RB26 . Because it shoots sparks longer.
The energization time cannot be changed without rewriting the ECU, but it means that the coil has the performance to withstand a long energization time.
The number of turns, materials, and structure of electric wires are all evolving.
Also, although it has a built-in power transistor, the price is much cheaper than RB26.
