Toyota 1NZ-FE / 2NZ-FE Ignition Coil – Genuine Bosch item


Ignition coil sold individually. The matching 4-pin connector kit is available as an option.


As well as being a factory replacement coil-on-plug ignition coil for various Toyota models fitted with either a 1NZ-FE or 2NZ-FE engine, these ignition coils are recognised as a popular choice for those wishing to convert a Toyota 4A-GE engine to a multi-coil (coil-on-plug) ignition system.


The Bosch coils have a built-in igniter (often referred to as a ‘smart’ coil), meaning a separate igniter module is not required.  Additionally in typical installations using an aftermarket ECU, only 3 of the 4 terminals on the coil will be used – the feedback signal is not required. For this reason, we offer the option of a blanking seal instead of the 4th terminal and normal seal.


Although the 1NZ / 2NZ coils are not a ‘direct fit’ for 4A-GE engines, their single bolt mount and overall dimensions do lend themselves quite well for use on both 16V and 20V 4A-GE engines with minimal modifications. Coil adapter plates and distributor blank-off covers are readily available from a number of suppliers.


Further to 4A-GE applications, we have also seen these coils used on other engines including Nissan SR20DE, Mazda B6 / BP and more.



  • Overall length = 147mm
  • Drop tube length = 118mm
  • Drop tube diameter = 24.4mm


Dwell vs battery voltage data is provided with these coils.
