Alright, I've searched and still haven't had a straight answer as to what we need.

Here are my findings:

Stock is Beru. They are too expensive or I can't find them.

Aftermarket options:
NGK: Laser Platnum PFR5G-11 NGK $9.50-$28.00 per plug
NGK: Iridum IV BKR5EIVX-11 $6.00-$16.00 per plug


Anybody have any experience with these plugs? Different plugs? I've heard that iridium are better, so why are they lower priced?

If you don't mind changing them more frequently and are actually interested in performance, sometimes expensive isn't always the best. Copper plugs tend to be the best performing, and they're about $1 a plug.

I don't mind doing work myself, so how many miles should I expect to get out of copper plugs? And please do tell where I can get copper plugs for $1 a piece. Is that what you use?

Pep boys! Remember, your car has two for each cylinder, so it's a PITA but it's kind of fun if you like doing the work yourself.

Send a message to Josh R and he'll give you the plug info.

Cool, will do. Thanks man!

I have the Iridium IX's. I didnt feel any difference in performance (I also have the evosport wires). I dont know, maybe I just didnt notice the difference or something. It was a pain in the a** changing the plugs and wires (I dont have many tools). The easiest way I found to do is take off the coil packs and you might need to remove the windshield washer jar (gives you alot more room to work).

Are iriduims supposed to be better conductors than platnums or copper? I guess, as long as you didn't feel a lack of power, that's a good thing.

Way to conquor the damn placebo effect!

You don't really need the iridiums unless you're running highly modified and need to run a tiiiiiiiiny gap setting due to high compression. Iridiums were developed to be able to produce spark in those conditions. At normal gap settings and anything short of a highly modified/high compression race motor, you're just throwing your money away.

Iridium is supposed to last a long time isnt it? (trying to justify the money I spent on it ). Evosport claimed an increase in power with these plugs and their wires so thats why I got them.

Think about it - if you use copper plugs and they last for about 30k miles, assuming you don't drive like me you probably put about 15k miles on your car a year - you're worried about spark plugs lasting longer than 2 years? Even if they did last longer, does that make them worth the extra 5-15 bucks per plug? If you have a 430, that's anywhere between 80 and 240 bucks you'll be saving if you change them out every 2 years.
