I tried to research this topic a few days ago, and the general concensus was stock plugs. Too bad they are rediculously expensive!!!
One of my factory plugs broke at 10k miles too.
I wish NGK would come out with the same plug as factory (but not sold as a mitsubishi) for 1/4 of the price.

Once I was pushing well over 400 WHP, I was having issues with the ceramics failing and dropping over the electrodes on the stock NGK plugs. I switched to Brisk plugs and they were the ****. Even after a catastrophic failure of my engine (snapped con rod) they were still 100% intact. None smashed, none eroded, none even fouled. Put about 1000 hard miles of testing and tuning @ 32 psi w/ a BB-X on them before that with 0 issues.
If you have to drop a heat range because you're making over 100 WHP over stock, definitely try the Brisk silver plugs. I've seen some bad reviews on them, but like with most things, it was probably user error. One thing you have to watch for on their plugs is the top terminal nuts; they come loose and may loosen as you install/remove the plugs to check them. Make sure to get them snug with a set of vice grips+soft rubber pad so you don't have any misfire issues.
If you're not running well above stock power, the stock NGK plugs are the way to go. In fact, they're the only ones available for this application minus the colder HKS and Brisk plugs.

Those are at least $45/plug. MSRP on them is $100 a piece!
Definitely not a cost-effective option unless they become mass-produced and the price drops.
For these NGK Racing plugs: R2556B-9 is one heat range colder than stock
R2556B-10 is 2 steps colder
Stock plugs cost nothing compared to these... and remember, most here bought a $35,000+ new car. A set of $75 plugs shouldn't be anything to you if you can afford and appreciate a new Evo.

Do plugs actually make a difference?
