Spark Plugs
I am planning on buying "Nology" spark plugs, with the spitfire wires from SR. But I am not sure if "Nology" is any good. If there is better please let me know, preferably with price per plug, and the part number for a 2002 Daewoo Lanos H/B. Thank you, and have a wonderful day.

Nology is Crap. I've had a set. At the first Nissan SE-R Dyno day that we were part of, they tested several sets of Nology wires on several nissan engines. Some with and some without resistor sparkplugs (nology says resistor plugs are required). All the cars lost HP and torque. Even with brand new plugs and new Nology wires, they all lost HP and torque.
Stay away from Nology and "direct hit" wires.

Thanks bro's for the info, so the other plugs are better than the brand new stock one's right. If so why are they better, I am trying to understand the whole spark plug thing. Thank you.

The stock plugs use cheaper materials.
NGK coppers use a more expensive Copper core. Copper is the best conductor you can get in sparkplugs.
Platinum plugs last longer than copper, but copper is a MUCH better conductor than platinum.
Iridium plugs last longer than copper, but not as long as platinum, but again, copper is a better conductor than Irridum.
The better the electrical conductivity of the spark plug, the more electricity there is to jump the gap on your plug.
You wouldn't use a poor electrical conductor in speaker wire or power wires, so not why use it in your most important electrical component, your spark plugs.

Actually, Iridium has up to 20 times more lifetime than platinums. And where are you getting this information about conductivity? Copper is obviously an excellent conductor, but you're getting into immeasurable differences. Plug longevity is really anyones only concern, unless they're using these plugs in a 2 second car.

I would have to agree with RANDOM and ONLY1DB. Check out Magnecor's web site http://www.magnecor.com/index.htm
They have a full write up on all the popular name brand plugs and plug wires. They stated Nology's plugs as being crap, and said that SplitFires Spark Plug wires were horrible at suppressing both RFI (radio frequency interference) and EMI (electromagnetic interference). Actually worse than stock wires.

Resistivity: (lower is better) And where are you getting this information about conductivity? Copper is obviously an excellent conductor, but you're getting into immeasurable differences. Plug longevity is really anyones only concern, unless they're using these plugs in a 2 second car.
[*]Copper: 1.7x10^-8 Ohm-meter
[*]Platinum: 10.6x10^-8 Ohm-meter
Not immeasurable wink Not insignificant either. Of course neither would be pure elemental metal in the plug, but the properties carry over into the alloys.
Copper is softer, the plugs erode faster in service. But long life is not the only consideration--spark quality is. The plug configuration can play a huge part in this--that's why proper gap is essential. Good plug design helps the spark. Copper also gives up its valence electrons at lower energy, its electron affinity is half of platinum's. This means that it will spark quicker when building from a zero charge--when you consider that each cylinder undergoes its full 4-stroke cycle in less than a millisecond while you're driving, leaving less than 1/4 of a millisecond to actually burn the fuel in a cylinder, the spark speed does count.
It's not just for racing--a cleaner burn helps fuel efficiency during daily driving and reduces hydrocarbon and carbon monoxide emissions.
