Spark Plugs

[mash]

I wanted to change the oil, filters, etc. in my R33 GTS. I also thought about changing the plugs.

I didnt know which ones to get, so i went to a few places and they told me i had to get Platinum plugs ($26 or so each).

Is that true? Do i have to get Platinum plugs?

Whats the difference between the Copper/Platinum/Iridium(or something like that)

If anyone knows the product number of Copper plugs that i can use, please supply.

Thanks in advance

You can use copper plugs. The advantages of Platinum and Iridium plugs is that they last longer.

I'm guessing the equivalent copper plug is a BCP6ES-11 (its the one recommended for the RB30)

Have a look on the NGK website (www.ngk.com.au) for more info.

just use coppers at 0.8mm gap and change em a bit more often - cheaper in the long run and better for street use. Theres been lengthy discussion about this in other threads you might want to check out - could be of some help.

u could try NGK BCPR6E but gap them at 0.8

about 4 bucks for one

i put platinums in my 33 and racked up over 100,000kms on the one set.

i just recently bought some copper ones thinking it would only make the car run better (being new plugs) ...no change.

The platinums i pulled out still look great. I'm half tempted to put the old ones back in and aim for 200k

I'll be going back to platinums... even if its only for the extra lifespan.

Thanks for the help.

i put coppers in mine..... car ran fine

put platinums in..... better mileage and probably my imagination, but smoother power.
