NGK Iridium plugs

[martroy]

I was thinking of putting some NGK Iridium spark plugs in my MP3. Did someone try that ? Does it make a difference ?

Also, it our manual, it says that we can use either BKR5E-11 or BRK6E-11 plugs in our cars. Does anyone knows the difference ?

Thanks,

The differences are the heat ranges. BKR5E-11 are the stock heat range plugs. BKR6E-11 is one heat range colder, and BKR7E-11 are 2 steps colder (recomended for N20).

So which one do I get?

I have a 2002 P5

I'm getting the Sparco wires next week, now I just need the plugs.
