Hey guys i've got a D16Y8 Civic and i was wondering which spark plug is better? Note im after better fuel consumption.
So far 2 mechanics recommended 2 different spark plugs

Issert? The mechanicthat recommended it to me checked with Repco and they said it was ZFR5J-11 ? I checked my manual just then too it says NGK BKR5E-11 =\

Omg that means i gotta put my old ones back in -_- the mechanic said that the NGK ZFR5J-11 is the right one and will use less fuel.

Ngk and my honda service manual Recomend the ZFR5J-11(normal driving conditions) or ZFR6J-11(Hot climates or continuous high speed driving) for the D16Y4.
