spark plug clarification/recommendation
i was recommended by an ebay dealer to use 4 trailing plugs instead of 2 ment for leading and 2 ment for trailing. this was after asking him if was really selling 4 BUR9EQ NGK plugs, i thought maybe it was a typo. has anyone heard of this.
im currently using the $100 set from mazda (which was recommended by the person who rebuilt the engine) that i currently have 23K miles on.

On a mostly stock NA motor you can run just about any plugs you want.
On a mostly stock Turbo car you want to run the 2XLeading and 2XTrailing or you can use the 4XTrailings
On a wild turbo car you will want to use colder plugs in the Trailing and possible even the leading
The Higher the number the colder the plug and the less change of detonation from a hot plug.
