According to www.ngk.com.au

Your Vehicle:

08/93 - 1998 NISSAN SKYLINE ECR33 (TURBO) 2500 RB25DET

Spark Plug Part No.

Recommended Plug PFR5G-11 <--Platinum Plug

Iridium Option BKR5EIX-11 <--Iridium Plug(up to 100,000kms)

My advice would be to buy the Iridiums as they are both around the same sort of price( ~$20ea) and the Iridiums will provide a better spark and last alot longer.

yes i have iridums they are good and i only paid i think $16 eash about 4 weeks ago from r+e auto, my other plugs were stuffed, could be why they were misfiring:)

Don't worry about Platinum or Iridium plugs, too bloody expensive! No more go, just last longer.

These are your choices!

NGK

Std Plug BKR6E $3ea

Twin Electrode (New) BKR6EK $6ea

Iridium BKR6EIX $16ea

Platinum PFR6G $16ea

Most are available like above with a standard gap of approx 0.8mm. This is the norm for a little more boost! You can go down to 0.6mm though.

If you add -11 to the end they are gapped at 1.1mm. Too much gap in light tune mods.

Heat ranges available are 5, 6 or 7 from memory, not sure why I have got mostly 6. Can't remember why, front of NGK book tells you what a lower number means!

Prices are from the best/cheapest shop on my side of Geelong! Platinum/Iridium plugs may be a little dearer now!

Always had great success with the BCPR6ES-11 in all RB20/25/30 engines.

Never needed a gap smaller then 1.0mm on all cars up to 230rwkw.

If you need small gaps, you must have buggered coils IMHO

BINGO !

Only reduce the gap if you are having problems with the standart 1.1 mm gap. With stockish boost, do not even bother. 0.6 mm for a bit of boost is ridiculous.

IIRC, the heat setting for a stock GTS-T is 5, do not get colder plugs if you don't need to.

Coppers are fine and cheap. You get a set of 6 for the price of a single iridium. Ask yourself why you need to spend x6 on spark plugs.
