NGK makes a great plug. TR6, or TR5. I have NGK IRRIDIUM(or however it's spelled) plugs. Don't remember the part number but, they would be great for any LSX powerplant.

HMMM. Perhaps martin could whip us up a nice matrix for which to use when.

based on:

+----------------+--------------+------------------+------------------+
|................|......tr5.....|........tr6......|......iridium.....|
+----------------+--------------+------------------+------------------+
|.stock..........|..............|.................|..................|
+----------------+--------------+------------------+------------------+
|.heads/cam......|..............|..................|.................|
+----------------+--------------+------------------+------------------+
|.supercharged...|..............|.................|..................|
+----------------+--------------+------------------+------------------+

Or something to that effect

I'd go with TR55's, they work well but don't last forever. Denso Iridiums are also good. If you have a supercharger you'd want TR6's or the Denso Iridiums.

I haven't had my stock plugs out yet, but the LS1's for the last couple of years came with NGK Iridium plugs re-branded for GM. So I'd bet the LS6 has these same plugs.

What about Plug Wires????????????

Almost ANY brand will be good for the LSX motors. Someone mentionded taylors,.... which you coudln't go wrong with. I have MSD's. Work great,...and I was able to find them in a JAM locally, which was nice. Since then, I have installed them on 3 CTS-V's....

When I do my coil re-location pack kit,...i'll use some taylors most likely.
