They are PFR6B11s or they would have the B or C on them.

Cheers guys it was a late night :)

So they are slighter longer than the wrong plug for your car? How do they compare to PFR6B-11C?

To summise PFR6B for NA cars only PFR6B-11c for standard and tuned TT zeds PFR6B-11B for tuned TT zeds

As long as it is a pro tem measure it will be ok, but long term it is a nono!

The same length as which plug and is the shroud cover the same?

Pete why have you bought NA plugs for your TT?

So why haven't they given them out to every British world champion?

NGK are the people to trust on this, it sounds like blueprint are copying an error (which nissan acknowledged) in the Nissan service manual.

I don't think people are being negative or dislike him, just that it is premature for a young person to receive this honour with lets face it, one world championship under his belt!

I have pondered over the ZRF7F-11, I presume they are colder than the PFR6B-11B, how do they compare in length Eric? Greg Dupree are now selling the colder irridiums, are they still only suitable with ported and polished heads with plug shroud removed?

Some info for you http://www.300zx.co.uk/forums/showthread.php?t=39441&highlight=pfr6b-11b

What Jap cars were fitted with oem is not relevant to the Uk as Jap fuel is very high octane, meaning they can run hotter plugs. Another factor is that NGK has different codes for different countries, so it is difficult to get codes from one small area of the world and use it for our situation. When I rang NGK and spoke to them directly they confirmed the only two plugs they recommend are the two I mentioned.

That article is not strictly correct, the correct plug for a standard car is a PFR6B-11C and one that is slightly uprated is PFR6B-11B. For seriously uprated cars there are irridiums in cooler heat ranges, but they do not last as long and I would only use them if circa 500bhp+

They usually like giving out awards at the end of people's careers/lives in case they caught doing something wrong!

Munny can I have a close up of your knob:wack:

Don't touch them!

Vinz thats not an extinguisher, that's your man pump :D

There are a fair few bankers out there making a bit of dough on the pounds downturn, but the politicians are laughing their *****cks off as it gives them an excuse to join the euro and I bet they won't lift a finger to save the pound!!!!

Have to agree with you, I think the powers that be do not like their minions displaying too much wealth!

What you need to do is to run the car in and then get it on a respectable rolling road, and they will inform you if the car is running lean or not!
