I just installed new magnecor 7mm wires on my disco 2, 2000. I used champion plugs, rc12yc and gapped them at .038. I was wondering if there were any better plugs to use that are already gapped with the magnecor wires? I noticed my disco doesn't have the same punch/power as before???? Due to champion plugs? Could it be that I gapped the plugs wrong? The champion plugs came pregapped at .032. Thanks....or should I have just left them the way they came?

 

Your gap is to big in my opinion.
Those plug wires and plugs are just fine.

 

Yep, should have left them at .032.

 

I read somewhere that the Bosch system requires a special plug. Supposedly, the tip is smaller than a standard plug and if standard plugs are installed, they will expand the ferrule in the plug wire and than not seat properly on the proper plug. True?

 

False.
They use a standard plug.
They came with the Champion copper spark plugs.
