Default spark plugs

I have an 04 cobra with intake, exhaust, maf, 2.76 pulley, and heat exchanger. I'm running 23 degrees timing. Which spark plugs do you guys recommend i use. I know i should use a cold plug to prevent detenation but, which plug do you guys recommend?

just dont get them. get exactly what i posted...... iridium is overpriced and doesn't work well with our cars. the ngk tr6's are cold plugs that work really well. and theyre pretty cheap, somethink like less than $2 a plug!

I always find it amusing when people make recommondations on what not to use but don't have any direct experience (I don't mean what your friends, friend, cousins, girlfriends, father experienced). What exactly is wrong with iridium?

I have them and use in both of my vehicles and I can tell you for N/A applications they're great. They stay clean, don't foul, and so far have lasted pretty long 30K miles on one set and hardly any wear. Now, if anyone has real world experience with iridium and FI cars, I'd love to hear it.

stock ones are fine on that set up. i used stock ones for quite a while with that combination. ngk tr6 gapped at .020 is what i used agter the port and they worked out great.

i used iridium on my f1-a set up! i always had problems with them!!! there were always misfires! the regular ngk tr6's work a lot better. for some reason the iridiums don't like to stay lit under hight boost applications. and YES! i am speaking from experience!
