It depends on the application. There are more and more better designs of plugs coming out, and more dynos proving certain plugs work better in certain applications. Try what works best for you. Most of the time, though, it is hard to beat NGK V-powers for price and availability.

I'm sure the ngk v-power's are the best bang for the buck, but i was lookin around and found these brisk plugs with a silver center electrode and have recessed grounds (to increase flame front) that are jagged to get a better ground.

Only lamborgini uses them on all their cars. I've found dyno sheets showing they average atleast 3.5whp and 5lb/tq increase. Prolly like 1-2whp and tq on my car tho lol.

But UTI students tested them on a mustang and got like 10whp and tq something crazy for a spark plug. Even turbo cars can find a great increase from these brisk plugs.
