・SplitFire's Super Direct Ignition System, SP-DIS-005S.
・The latest ignition system, "Direct Ignition," overcomes the weaknesses of the genuine coil, and is a high-power ignition coil.
・Unlike the genuine ignition system, the ECU directly instructs the coil located for each cylinder. As a result, the amplified voltage does not lose voltage when it passes through the spark plug wire to each super plug via the coil, and the amplified voltage can be transmitted more efficiently.
・The high-performance ignition system "Splitfire Super Direct Ignition," aimed at further increasing potential, prevents a drop in secondary power by increasing the number of coil turns, changing the coil winding ratio, and changing the iron core material, thus preventing energy loss at medium to high RPMs.
・For RB/SR, it is based on the normal direct ignition system, and for B6/BP, it is the normal system changed to direct ignition. Both can supply high voltage and stable electrical energy to the super plugs across the entire RPM range, preventing a drop in secondary voltage at high RPMs.
・The difference in capacity between the normal spark and the Splitfire Spark Ignition System's spark is immediately apparent, promoting complete combustion, resulting in increased power and torque, and even lower fuel consumption. Furthermore, because it employs a low-voltage operating circuit, it exhibits excellent starting performance even during idling when starting the engine or in situations that cause voltage drops.
・It is designed specifically for each vehicle model, so it can be installed with a bolt-on method.
*Ignition coils are consumables! Prolonged exposure to high temperatures will gradually reduce their performance, significantly affecting engine performance and fuel efficiency, so we recommend replacing them during vehicle inspections or regular maintenance. 《Super Direct Ignition LINE UP》 Main compatible engines Product number Skyline (R32 etc.) RB type SP-DIS-001S Skyline (R33 etc.) RB type SP-DIS-005S Silvia (S15) X-Trail GT (PNT30) SR type SP-DIS-007 Skyline (R34 etc.) RB type SP-DIS-008S GT-R (R35 etc.) VR type SP-DIS-103S
