1jz-gte head is too tight for LQ9 coils and require grinding a little bit on the head (on each side of the coil)
2JZ-GE will require front facing intake manifold because this wont clear the factory intake that goes over the cam cover.
This is NOT plug and play with the factory ECU. It’s possible to use them with factory ECU but an external box is required to generate the IGF signal.
The toyota igniter is NOT needed with these coils!!!!
It’s best to use them with a standalone.
Use with BKR7E spark plugs.
