I've used both plugs and never had any issues with them leaking or anything like that if that's what your wanting to know.

i wouldnt use OD plugs in jammin engines, it wont run right, OS P4 is the way too go... or picco plugs are best.... the jammin engine is the only engine i wont run OD plugs in, i run OD plugs in all my engines except for the jammin engines...

sometimes they leak, sometimes they don't..... IMO the best bet is to run either Picco or Werk's plugs...
