The SplitFire Super Direct Ignition System is designed exclusively for the Japanese T high performance engine.

This system replaces the original equipment coil pack and ignition wires with a direct ignition coil on plug system. The increased ignition performance found with the SplitFire Super Direct Ignition System is a must for all racing and performance enthusiasts.

Please note Coil packs can take 2 weeks to order in from the maker. There is a 30% restocking if a cancelation is made once the order is processing

  • Increases horsepower at the top end of the RPM band

  • Ensures and maintains maximum energy supplied to the spark plugs

  • Reduces incomplete combustion caused by misfire

  • Eliminates RFI (radio frequency interference) by eliminating the need for a wire set

  • Easy installation designed to fit the high performance engines

  • Option RB20DET harness required for older vehicles, see the details from Splitfire under Links below.

Please Note. The difference between the RB25DET series 1 and series 2 Splitfire coil packs are the igniters. The series 1 have separate igniters, where the series 2 are built in. You should be able to tell by looking at the existing coil packs. Alternatively you could look up the engine number with Nissan.
