ok im goin thru all of the learning stages of modding a turbo motor. with the 440s my plugs dont last very long, but the car was pulling fuking hard! alot harder than with the stock injectors. the first time i drove the car with the 440s and after i hooked up the spearco, i was loving it! until the motor flooded out with the gas. after dealing with the injectors and realizing my ecu was bad, i borrowed another ecu and put back in the stock injectors (everyone was tellin me to swap them back) so i did it and drove the car a few times. it was nice, but it pulled alot harder with the 440s.

the point of this story is, i wanna put back in the 440s but dont wanna deal with the plugs fouling out after a few pulls. i was using ngk 3330 and the heat range is 7. i didnt gap them either. they were already pre-gapped to about 30-something degress.

what can i do to make those plugs last??? like i said, i just want my car to pull all the time like how it did for those 30secs with the 440s.

my only mods are the ebay ypipe/downpipe, greddy sp catback modded to fit cressida, spearco intercooler (same core size as 7m drop-in).

i have a turbonetics vbc and greddy emanage blue brand new in the box. but i wanna know if theres a way i can just put the injectors and perhaps use different plugs to prevent then for not lasting long. i didnt wanna hook up the emanage yet cuz ill be selling the harness soon and didnt wanna hack it up.
