I was just wondering if these plugs would be okay for my 50shot set up. I honestly don't know if they're for the WRX, the seller is throwing them in and he used the kit on a Type R. What are the best/cheapest plugs I should get for my nitrous equipped WRX running 16lbs of boost?

That would be a copper core, one step colder than stock, replacement plug for your EJ20.
Those should do the trick.
Don't use platnium plugs with nitrous, don't know about iridium.

Exactly what Scotty said. I use BKR7ES-11(copper, one step colder). Don't use the BKR7EVX-11, it's plantinum. Also make sure you use 37 nitrous and 22 fuel jet to start...that's the jetting for the wrx kit.

Don't get the -11's..they are pre-gapped to .11mm(~.044") and to get the proper gap the electrode must be bent too far and poor performance can result.
The BKR7E is pre-gapped .7mm-.8mm(~.028"-.031") and are prefered for this reason.
I got mine(had to be ordered) from NAPA for $1.99ea.

So they are just BKR7E? nothing else? I did have to gap mine way down, no problems but good to know for next time.

thanks

Yeah....no 'dash number'....Just:

BKR7E

Do not use Iridium. The electrode will melt right off and cause Nitrous backfires and mis-fires. Bad, Bad, Bad.

BKR7E is the way to go :)
