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.

What 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.
i found BKR5E-11 that the prevous owner put , but the engine jerks a little bit
so i tought to check

Measure the threaded hole length to see if it uses a short reach plug base or a long reach plug base. You may have the wrong plugs installed.

If it's a QG engine, it should be the LFR5A-11 (Stock # 6376) gapped at 1.1 MM (or, 0.044-inch). That would be a Nissan V-power series plug. If you want a longer lasting plug, you could also use an NGK Laser Platinum series plug rated for 105,000 miles; it would be a PLFR5A-11 (Stock # 6240).

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.
