Are the Champion Premium (or premier?) any good. Noticed that they're a lot cheaper than the equivalent NGK or Bosch.
And is it worth the effort changing plugs yourself rather than getting the (rip-off merchant)dealer to do it?

 

I think people generally recommend sticking with the standard items.

 

Yep NGK, DON'T buy champion

 

NGK definately, get a quote on replacing plugs should take 30-45 minutes...............
