ISR Performance OE Replacement Ignitor Chip - Nissan SR20DET S13/S14

The ISR Performance OE replacement ignitor chip is a direct replacement for the factory ignitor on the Nissan SR20DET in S13 and S14 240SX chassis. The ignitor is the switching module that fires the coils on command from the ECU, and when it fails the result is a no-spark condition or a car that cuts out with no warning. Finding a reliable new ignitor for an SR has been difficult for years, which is exactly why ISR added this part to its OE replacement range.

Developed, then tested

ISR did not rush this part to market. The ignitor chip was tested thoroughly for months before it was released to the public, so it has already seen real heat and real driving on SR20DET engines. With the success of its other OE replacement items, ISR has committed to supplying more of these hard to find JDM pieces.

Signs your ignitor is on the way out

• Intermittent stalling that gets worse as the engine bay heats up
• Sudden no-spark on all cylinders while the coils test fine
• Random misfires that do not follow a single cylinder

Compatibility

Nissan SR20DET, S13 and S14 240SX applications using the factory ignitor and coil pack layout.

Install considerations

Mount the ignitor with a clean contact surface so it can shed heat, and inspect the connector pins for corrosion before plugging it in. If you are chasing a spark problem, check coils, plugs and grounds alongside the ignitor so you replace the right part.
