RE: best spark plugs for APR chiped 00' A4
worry about what?? Copper makes the best spark and provides best resistance for forced induction engines where highly compressed hot air (boost) is passing by the spark. It also reduces your chances of detonating (lean condition=very BAD.) The .028 gap is also best to have for high boost because that much psi of boost can actually blow the spark out if the gap isnt tight enough.
Time? It takes 10 minutes to change out spark plugs! and if you cant spare 10 minutes every 15k miles, well you are a poor time budgetor.
I noticed much smoother engine operation when i changed from my plats with 1k miles on them to coppers in all rpm ranges from idle to redline.

A helluva lot cheaper... BKR6E at autozone is like $1.79 a piece. Compared to almost $10 a plug for the plats and the coppers do a better job, but need changed more often.

i asked how much more ofter...there's no quantitative info about how much more often (miles) they have to be changed compared to the platinum plugs, just that they have to be changed more often...kinda ambiguous info. i go by the maintenence schedule that came bundled with the car manual, and i'm assuming that they wrote that specific to the car containing factory components including spark plugs. so if i change the spark plugs, the frequency that i have to change them changes also and all i'm trying to figure out is; after how many miles should the copper plugs be changed?
i should have posed the question better in my other posts.

basic rule of thumb, for every 50hp you add to the engine, you gap the plugs .004 closer
stock : .032
chip: .028
etc etc etc
and if you get enough power (bt) you drop down to the next coolest temp range ie bkr7e
