I was wondering if anyone knew what the construction of the stock plug wires is?

The shop manual says that they should have less than 19,000 ohms.

On that short of wire that sounds like a carbon core.

I have read that the Magnacore does not fit well.

I have some of their wires on another car, they are great wire, solid silcone from the outside to the conductor. But if the boots don't fit, they are not going to work.

NGK ME96 is a $23.00 wire set that is supposed to fit 99-03 4AG64 engines and others with coil packs.

NGK also makes a "Power Wire" that is blue and has a silcone outside jacket and sprial coil construction. I think they are the basis for the "Ralliart" wires.

If the stock are sprial coil construction not much point in changing them. If they are carbon core, they should be replaced.

If anyone knows the answer or has some stock wires they want to sell cheap for destructive testing, let me know.

Thanks

i am also debating this but have a deal on Apex made by Apexi which apparently is made by NGK and is their Power Wire

 

I had zero luck with the Magnacore's. Ive had two sets of these wires, both new, and they both caused a misfire situation.

 

I have seen other reports of problems with the Magnacore wires.

As near as I can tell, this is due to fit problems on the boots, not so much the wires themselves,

Magnacore is great wire, but if it doesn't fit properly on the coils or plugs, then you will get problems.

If I hadn't seen people reporting problems, I would have ordered a set.

I have been using a set on another car for 10 years, with headers, no problems.

i got the Apexi which on the box says made by NGK
Next time I check the plugs would change them out and see
my car has approx 18k miles on it
would also do a resistance test to see what they both got and would let u guys know

 

Well I did the install finally
short stock wire reading was 2.78 and multimeter seting was 20k ohms so this wire read 5,560ohms and the long one was 5.86 which would be 11,720ohms
Both within spec
Apexi made by NGK, short one was 0.4 and long was 0.6
Car working good all the time
Just found was a lil quicker response, SOTP btw
Fit was EXCELLENT

 

If that is a digital multimeter you are using - I think you don't have to scale the reading.

If you are set to 20K Ohms and the actual resistance was 11,700 it should just read 11700.

I have not seen your meter, but I bet if you set it to a 10 Ohms range it would read the same 2.XX as it did on the 20k ohm scale.

Did you cut up the stock wires and see whats in them?

ok i may have it wrong then but definitely was 20k setting

nah, they are working and won't have damaged them on purpose

I am pleased with them. Will monitor gas mileage and see any diff.

 

FYI - NGK ME96 wires do not fit Evo IX

Bought some and tried it.

Sparkplug rigid black plastic boots are too long to work.

About 1.5" / 38mm too long.

Look like good wires, but no go.

just cut open a OEM plug wire.... mmmm, destructive testing

its a spiral coil design....

 

Good info,

I checked the resistance of the short NGK wire (Known Spiral Coil design) and the factory short wire design.

NGK 2.40k Ohm

OEM 2.74k Ohm

So your info confirms what I expected after the Ohm reading. Not much to gain from changing the wires.

Since the air gap at the plug will be thousands of KOhms, the wire is trival.

Now I got to send back the NGK wires that didn't fit.
