What is the spark plug of choice?
I was thinking of NGK Iridium IX Spark Plugs. What are some of you guys using in your VQ's?

Come on now, there are hundreds of posts about plugs...Read one of the many threads and you will see that 99% of the people will tell you NGK plats. Not to be a smart a** but read the stickies and prior posts before you ask a question.

He's wrong. Ignore that post. You can get any spark plug in stock or colder heat ranges. The facts are that coppers are cheaper and don't last as long. Performance-wise you won't notice a difference between copper/iridium/platinum, so there's really no point in getting more expensive iridiums or platinums unless you really hate changing your spark plugs or something. Technically copper is the best conductor of the 3 metals, but in reality the difference would be so minimal as to not be noticeable at all. Iridiums are better for high power boosted applications which have much much higher cylinder pressures. Colder heat ranges are likewise for boosted applications.

By the way, NGK lists 2 types of platinum plugs: Double platinum - part #PFR5G-11 - $11.71 and GP Platinum - part #BKR5EGP - $2.68

#BKR5EGP G-Power are real platinum as well, they have platinum center electrode only, whereas #PFR5G-11 have laser welded platinum tip on center electrode and platinum tip on the ground electrode. Basically, the more expensive plugs have higher platinum content.

I have 57,500 miles on my OEM platinum plugs and my car runs like a top. I believe many orgers run in excess of 60 K on their platinum plugs. Does the performance when running NGK copper plugs go downhill prior to 30 K, say between 25 and 30K or whatever.
I guess what I am saying is that the lifespan of the platinums could be in excess of 60K whereas the lifespan of the coppers is less than 30K without compromising fuel economy.

so platinum 78,800 mi and counting.

why the hell would you do that? iridium plugs are better than platinums in EVERY aspect - service life, conductivity, melting pt. the only reason why our cars came with platinums was because iridiums weren't available then.
