Thanks guys, think I will take you advice and change the plugs to a 6. Probably keep the platinum's though as i will be checking them every 5-10 thousand Km's!

Hi ppl,
So i got new spark plugs going in tomorrow for the 33 gts-t (NGK PFR5G-11). However car is modified by 50 or so horses. Do i go colder? (NGK PFR6G-11)

Hah, same problem with mine but RB25DET. However going to get the place i bought it from, to investigate all the things u outlined. Warranty job! Could it be timing also?
