Anyone know off-hand the gap size for the spark plugs in a QR25DE Spec V? Also need to know what kind of plugs work best with these engines. I found the copper V-Groove plugs worked best in my RB20, is this true for the QR’s as well? Or should I go with iridiums?

Nevermind, found it in the FSM:

PLFR5A-11 \>OEM  
PLFR4A-11 \>Hot  
PLFR6A-11 \>Cold

Gap: 1.1mm or 0.043in

I have iridiums… No diff from OEM that I can tell.
