D3 petrol 4L V6 - spark plug and lead recommendations

[twr7cx]

Had a look through the sticky section and read the thread on service stuff but couldn’t find the answer in there.

In regards to a D3 with the petrol 4.0L Ford Cologne V6, is there any particular brand of ignition plugs and leads that they prefer or any to avoid?

I picked up a set of these 6 New NGK IRIDIUM IX Spark Plugs TR55-1IX # 7316In the US last week - hopefully, they are the right ones.

Not sure about leads though.

old thread but the new plugs went in last week - seems smoother running but then the old plugs were at 130,000km
