ive had good luck with NGK Iridium spark plugs....i used to use the cheapest copper cored ngks and bosch supers cause they were cheap, but they kept being blown out at boost pressures higher than 8psi (and they were gapped pretty close), the Iridiums tend to hold their spark under higher intake turbulences. they say for every 75-100hp over stock you take one step colder on the plugs.
