but i have the manual of primera p12 it shows : NGKTaken from the FSM of a Primera.
Standard type: BKR5E-11
Hot type: BKR4E-11
Cold type: BKR6E-11
i found BKR5E-11 that the prevous owner put , but the engine jerks a little bitWhat plug type do you have in the engine now. Is it one of these:
NGK Standard: LFR5A-11
NGK Cold: LFR6A-11
NGK Hot: LFR4A-11
The recommended type is NGK standard LFR5A-11.
Rogo, you probably had a manual for a P10 or a P11, which has the GA-series engines that took the BKR5E-11 spark plugs. The P12 Primera's went to the QG engines and the GA's were dropped.I think you may be right. The FSM I was looking at apparently had incorrect info in the MA.PDF section. I notice that every now and then FSMs sometimes have misprints. My bad.
