Toyota 1JZ-GTE/2JZ-GTE (turbo, 6cyl 2.5 or 3.0 litre) are all Coil-on-Plug and require an external ignitor.

Am not sure if they'd cope being driven by a waste-spark pack like EDIS (1 ignitor per 2 coil-outputs) - Toyota does drive them in pairs but with one ignitor per coil.

i think he means that if you get a non-screw-in IAT sensor, just drill the guts out of a plug, screw that plug into the intake somewhere and then glue in the sensor into the newly drilled hole.
