are you after model numbers, or just types of plugs, ie. copper/iridium?

i used NKG copper plugs in my 33, and in my gf's stag, model number is BCPR6ES.

hey i need new plugs for my 32 and was thinking going down the copper path..if u dont mind me asking how much r they each and how long do they last..as ive herd u have to change them more often than say the platnium or iridium ones but they give a better spark as copper is a better conductor of electricity

I have found the coppers to last not much longer then 10,000kms. 33 with cat back

As for price 20-25 bucks for the lot.

copper ones are about $3-4 each, but only last about 5,000 - 10,000km, however they do give the best spark.

then you have iridium which are about $30-40, last 50,000km? and give a slightly weaker spark

and then there is platinum, no idea on price, but they last about 100,000km and give a weaker spark again.

i've only ever used copper, however i'm contemplating iridium as the rear 3 plugs on my legnum need the plenum removed (not as hard as it sounds though).

coppers are meant to last 15000km

irridiums are meant to last 90000km but rarely do without trouble.

and yer copper is not recomended for forced induction but alot of people say thats not true..

i have used copper in all my cars de+t and everything they are ok but dont last long.

i have found irridium to be a little better when the car is running hot, otherwise i havnt noticed any difference.

copper are $3.50 each

irridium are $20 each

ps i should have known it would be the same scenario as my ca..

but thanks guys help is much appreciated

oh and i was also wondering on what model number people had tried out and what the results were..

i know for a higher boost application the bcpr7es11 is recomended for the different heat etc..

thanks to the guy who pmed me also
