Changing Spark Plug - 1996 Es300

[wan8dan]

Hi LexusClub members,

I changed spark plugs for the 1996 ES300. It was a lot of effort as the 4, 5, 6th spark plug valves are hidden under the main air manifold and required taking them out to reach for these spark plugs.

Strangely, I realized these 4, 5, 6th spark plugs do not have spark plug coils on them and there are no electrical wiring for the coils either. But the 1st three spark plugs in the front do have coils and the spark plug cables are connecting directly to the 4, 5, 6th spark plugs.

Is this normal as expected?

Thanks
