Spark Plug question

Motorfiets · 05-02-2011, 04:10 PM

I have two unused ( 12 12 7 664 404 or DR8EB ) spark plugs anyone know if these will fit the F800GS?

No, I wouldnt.

The replacement plug is a DCPR8E or a DCR8EIX(iridium plug)

The 'P' is projecting insulator type

The 'B' in the plug you have means "integral terminal"

Best to stick with what is recomended.

Has anyone ever taken their plugs out and inspected them? I tried twice and do not seem to have a small enough (diameter) socket to reach down and do the job....I cannot believe that BMW requires a "special" tool to remove the spark plug, anyone got any ideas, My spark plug socket, cannot remember which size, but it fits so tightly that I cannot turn and remove the plug?

Its not so much a BMW special tool, more so the correct tool to fit the plug, due to it being a thin spark plug. The joys of double overhead cam engines with a central firing point for the spark. I thing a 16mm deep 3/8 drive single hex socket will get in there and get it done.

Don't you need a special tool to remove the coils?

No, just turn to break stiction, then pull. I don't posess the special tool and it hasn't slowed me once

They do make a special tool to remove the coil packs, but you can wiggle them off without.... I got the tool but cannot remember where, it was not much... by hex you do mean 6 point correct not twelve point?

Yep, single hex = 6 point
