Thats madness money
Those HKS ones aren't too expensive considering NGK Iridium ones are like £60 anyway. For the record I have NGK PFR7Bs in my classic STi. To the OP it would depend on the mods you done to your WRX if its standard i'd get NGK PFR6Bs if its modded i'd get the PFR7Bs due to the higher heat range.
