Champion plugs seem to work fine as well.

Best advice is to use a direct replacement, nothing platinum or multi-tipped.

What about Iridium plugs? or Nology Silver tips?

I will probably use them with Nology wires.

From what I have read, silver or copper only.

Just stumbled across this thread..

As for spark plugs, the super basic NGK is the best, Iridiums dont do crap unless your motor was designed for them.

It has been dyno proven that NGK spark plug wires and MSD wires are the best you can buy, all the others (magnacore, nology, ect.) result power loss. TPR magazine did the test back in '04, link.

I know this has already been said, but I read somewhere that the super-dooper multi-electrode plugs result in hot running, rougher idle, and lean burn. Not sure why they would cause burn problems though...

IIRC, it was in some letter in Roundel or Bimmer

Forget plug wires.
Go Coil On Plug. Cheaper and better.

No plug wire is better than any plug wire.

I have even used el cheapo A/C Delco copper plugs with no ill effects or loss of performance. I think the Bosch plug wires may be expensive because they fit the OEM BMW setup. I've seen a lot of Magnecor wire installations that had eliminated the plastic piece in the center of the valve cover. It seems that BMW may see a performance advantage to coil on plug systems or lower parts cost. Possibly both.
