Needs plugs and wires, NGK LFR7AIX?
I have an 03 E55 and need plugs and wires. From the research I did, it looks like the NGK LFR7AIX plugs are the best for these cars, how about the the wires? Just stick with the OEM BOSCH wires? What are PRENCO wires on ebay? Any good? TIA

Currently stock but I do want to do the euro charged tune and pulley and intercooler, but down the road and that's maybe. So which should I do? Also should I just forget about the Bosch oem ones? I'm going to stick with the oem Bosch wires but shouldn't the Bosch wires be a good match with the Bosch plugs better than with the ngk plugs?

You are changing wires along with plugs ?
I was under the assumption that wires don't need changing until unless they are to be changed depending on condition ?

When checking on the NGK (2309) LFR7AIX Spark Plug Amazon keeps telling me "This does not fit your: 2004 Mercedes-Benz E55 AMG"
Being in Australia wouldn't make a difference in the plugs that came stock would it? Or is Amazon being pedantic since they are colder than the originals?

check my link in the parts list:
Magnecor 85240 8.5mm KV85 CN Series Ignition Cable 1997-2011 $172
note: this is the 8.5mm part, need to find the 10mm part (if you're interested)
Magnecor's KV85 Competition (8.5mm) and R-100 Racing (10mm) Ignition Cables feature Magnecor's exclusive 2.5mm high capacity Metallic Inductance EMI Suppressed conductor consisting of stainless steel wire precisely wound at 200 turns per inch over a ferrimagnetic core. The insulating jacket is made entirely of Magnecor's exclusive TC-1500-HS high strength aerospace grade silicone rubber, and its single layer construction will prolong the jacket's insulating ability by conducting extreme heat away from hot-spots that occur near over-the-limit heat sources.
The KV85 8.5mm jacket has a service heat resistance of 600 degrees F (320 degrees C) and up to 1,000 degrees F (540 degrees C) for short burst 3 minutes. The R-100 10mm jacket has a service heat resistance of 700 degrees F (380 degrees C) and up to 1,200 degrees F (650 degrees C) for short burst 3 minutes. Even if limits are exceeded, the silicone rubber will retain its insulating ability until wires are removed from engine.
it seems the 10mm is just more insulation, not more core
