Poll: Spark Plug Change...How often?

I'm sure there is one of these around, but I looked, I promise.
Seems to me, my plugs are shot at about 10k on my N/A. I also have bad experience with running anything other than the BUR7EQ and BUR9EQ plugs.

They eat plugs.Let's not forget that for every revolution the leading plugs fire 6 times, trailing 3. Compare that to a piston engine 1 revolution 1 fire. You can see why the plugs don't last.

I change mine about as often as I change the oil. I wouldn't say I have money to burn, but they're usually only around $4 or $5 each.

I have heard of stock NGK plugs going for over $10 American...I guess some places just don't want to stock them.

Thanks for the replies and not calling me an ******* for not putting this in the polls section. Although it IS 2G spec...

Just thought I'd put the poll up today because I'm well over 10k and recently my beast has been running a little rough (warm startups mainly).

Better change 'em before autoX this weekend!

Great, now I'm not unique any more.

Have any of you guys used plugs other than the BUR9EQ and BUR7EQ?

10K is when I change mine, I think it's ok to go as long as 15K, but no more than that..

On the RX7 now, every 3 races is what I've budgeted.

I change them every other season. With a Crane Cams Ignition Box amplifying the sparks, I would think maybe I should change It sooner.

Lately on my FD I've been changing them all the time. I only got 200 miles out of the last set....that's probably cause I let the car sit and they fouled out....oops.

Apparently, some people think the stock plugs are worth a lot of money.

What are you talking about? FC's didn't come with CDI from the factory, and each rotor face combusts once per revolution.
