Hey guys I was wondering if it was safe to use NGK6E's in my 1JZ or should I stick with NGK7E's? Reason I am asking this is that I have fouled 2 sets of NGK7E's so far.
For instance, I put in a brand new set of NGK7E's last night and put about 60km's on the car. My AFR's were not too bad cruising around mid 14's and a little rich under light boost mid to high 11's. My idle was around mid 12's which was a little rich so I leaned it out a bit.
I go to start the car this morning and it doesn't start.I figure the spark plugs fouled on me because it has happened before.
