i'm looking to buy a set of NGK Iridium (2 step colder) spark plug.do you know where i can get them fast? thanks

Do you have the part number?

I use sparkplugs.com they ship pretty fast, but I don't know the right part number.

no i don't

http://www.clubplug.net/

they have links to the major plug manufacturer websites so you can find the OEM part #. finding 2 heat ranges colder shouldn't be too hard after that.

example:
2004 INFINITI G35 3.5 V6 VQ35DE FI
Iridium IX - part no: LFR5AIX-11

here are the important numbers in bold... LFR5AIX-11
the "5" designates heat range. the "IX" designates iridium. the "11" designates the preset gap.

thanks russ.but that part i know.so far i found NGK 1step and DENSO 2step
the NGK 2step no where to be found.that make me believe they haven't made yet.i'll confirm with them tomorrow when they are open.

NGK does make two step colder
part# LFR7AIX
stock# 2309
thank you all for your replies
Steve.
