Splitfire Nissan Super Direct Ignition System DI Coil Packs suits many Nissan models 1989-1995 incl R32, R33

Splitfire Nissan 6 cyl. Super Direct Ignition System DI Coil Packs
This system replaces the original equipment coil packs 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.

• Standard ignition systems may burn 90% of your air/fuel in the combustion chamber
• The new Splitfire Super Direct system can burn 99% of your intake mixture producing the MAXIMUM power
• 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 high performance engines

NEW Splitfire Coilpacks to suit most BMW vehicles Splitfire are well known for their Super Direct Ignition System, replacement for often worn coilpacks in Japanese vehicles.

Splitfire also now make Coilpacks for most BMW`s delivering an average extra 5ps to the vehicles performance.

While various high performance car parts such as computer, muffler and turbine are available in the market, there were no drastic improvements for ignition system. It was limited to tune the mechanical ignition system which distributes electricity from the coil to each spark plug through spark plug wires.

Then Direct Ignition System was designed. This is the system that ECU directly sends the electric signal to each coil on the top of each cylinder for ignition.

The best ignition timing is obtained by the sensor and is controlled by ECU and fuel injection system. It makes an ideal condition for ignition and enables to provide a constant and stable electric power at all RPM.

Thanks to the advent of an original ignition system, ignition system made tremendous progress. However, this system left a weak point. That was a reduction of secondary voltage at high RPM. Because of the restriction in design, genuine coil packs were not able to produce enough energy.
