tune up parts

[5thAve]

Has anyone ever tried V-groove spark plugs? How about the Wells 'gold' cap and rotor kit? I got all the stuff today to do the badly needed tune up on my 5th, I figured since everything is out of the way while I'm changing the valve cover gaskets now would be a good time. Anyway the new cap was poorly made and is WAY off centered and the plugs aren't the right ones either so the tune up will wait til monday. The Canadian Tire v-groove plugs (made by a real name company) are the same price as the real name ones I'm going to be returning, and the cap/rotor kit is only $4 more so I probably will end up getting these parts.

I was just wondering what experiences others have had with these parts, (draw backs, performance advantages, etc...).
