    Measurable difference? An Ohm meter will show differences, whether the car actually performs better depends on how bad the stock wires were to begin with.
    With these cars as old as they are now, if you were still running stock wires it's probably a good idea to swap them out anyway.
    Agree! Even if the car does'nt get driven much and has low mileage the factory wires maybe dry rotted or starting..

    Side note I think sometimes "sitting" is worse for a car than driving it..

    This will be my first year garaging my car. When you garage a car for the winter, how often should you start up the car? Or should it actually be driven? Are there any other things that should be maintained during that time?

    I will start mine maybe twice all winter sometimes not even that.. I would'nt drive it with the salt that gets used on winter roads.

    As far as maintaining things goes, I'd just keep the tires aired up so not to have the weight of the car come to bare on the wheels.. Temp changes can sometimes cause a tire/s that does'nt move to go flat or loose some air over time.. I would also treat all your door/hatch/hood/t-top, seals and wheather stripping with black magic... Yeah that's right tire wet.. Been doing this for years, and is good preventative maintainance..

    I try to start ours at least once a month and let the engines come up to temperature. I also will cycle the AC or defroster as that helps keep the seals in the AC system lubricated. I move things around in the garage over the course of the winter so the tires and driveline do not set in the same position for 6 months straight. If dampness is an issue, keep the windows cracked to allow some air circulation through the interior. If mice are a problem, I have heard of people using mothballs under the hood to keep them from munching on the wires and building nests.

    NO! Bro don't use mothballs! I mean EVER.. They will taint every inch of your interior fabric and you CAN NOT get rid of the smell....

    Underhood only. I would never put them inside the car.

    NGK 6ix's for me (Iriduim Tips) and MSD wires. Did them while, i did my headers, Catted Ypipe, and new o2's after hitting 100,000 miles. Car ran like a champ.

    Ya, if you don't care to change your plugs every 10-12,000 miles you are better off going with an iridium or platnum/double platnum plug. They are made to last as much as 50,000 miles or in some cases they claim 100,000 miles if you dare to run them that far.

    Your standard run of the mill copper core plugs such as your NGK TR5's and 6's or the autolite AR racing plugs generally go about 10,000 miles before you start to see electrode wear, and plug gaps start to increase.

    I hear ya. I just put in the AC Delco Iridium 41-110. Plugs are relatively inexpensive, so the little extra money for the better plugs will actually save you money and you will have better performance.

    Copper is a better conductor of electricity. Technically the cheaper copper core plugs, or racing plugs will give you more spark in the chamber. They are also a better choice for power adders such as nitrous. To keep performance at it's peak, these plugs need more frequent changes, like I mentioned 10,000 miles or sometimes less. If you don't stay on top of them then performance over time could deminish.

    The Platinum plugs have more resistance to put it in simple terms, and they are not recommended for nitrous use. Not necessarily better performance, unless you are the type that doesn't like changing plugs, in which case in the long run, say 30K miles or more, they would provide better performance over a copper plug that has been left in too long.
    Platinum is more of a maintainance free plug so to speak, more than anything else.

    Right. And the iridium would have better performance at 50,000. As you can probably tell, I don't like changing my plugs.

    I don't blame ya. These cars aren't the easiest things to get your hands down into.

    The driver side no problem. The boots didnt want to come off on any of the plugs and they wouldnt twist. Not alot of room to get leverage. The passenger side #7 was a pain. I just squeezed my hand down the sid eof the engine and it just made it to the last plug. Had to do everthing with 2 fingers. More something I needed to do, not wanted too. Once I do my trans service and oiul change, I will be able to get her back on the road. She has ben sitting up in the garage for 2 weeks. I installed AC Delco Iridium plugs, new OEM delphi wires, SLP lid, Rebuilt the alternator to 180 AMPs for the stereo system, upgraded battery, new tires, new fog and parking lenses (115,000 miles started looking foggy and had cracks) and a diablo sport predator tune. I think she will drive a little better. Hoping for about 25 HP between the lid and tune.

    I stay away from the NGK's, we didn't like how they performed on the dyno. Didn't seem to matter what heat range we went with, we couldn't get a variation in EGR's, they all performed like a hot plug, so they were thrown in the trash. They can send those things back over seas where they came from as far as I'm concerned.
    ACDelco plugs are good quality, but they have swapped around part numbers, some popular numbers aren't even available anymore, and in the process they stopped offering various heat ranges, so I stopped using them as well.

    On the wires, I run MSD wires on several cars and have never had any type of radio interfearance.
    They are a Japanese company but the spark plugs are built in Sissonville WV. Won't change your experence with them but for those wanting to support American workers you can buy the NGK's
