I have a 1990 Nissan 300ZX Twin Turbo and need to replace the Sparks.

I read that I only need to install NGK PFR6b-11b ones, but there are also 11c ones available and the Nissan garage says that it has to have the 11c types.

 

Which one do I really need?

11c was fitted to UK spec. 11 without a letter was Jap imports.

NGK PFR6b-11c, are the correct ones for European zeds, the US guys always say the 11b are better but it is more to do with the petrol grading they use.

So 11 with or without a letter is ok?

My Nissan is now runnning on 5 cilinders, so that does not drive very well.

I want to start with changing the spark plugs.

 

The garage thinks it maybe durt in the fuel, but I doubt it.

NGK code is 4014 I found they were cheapest.

How so. Pfr6b-11 is correct of imports no?

 

"PFR6B-11 ( without the C ) are fitted as stock to Jap import TT and Non turbo for use in Japan.

Who said it's a UK zed

Not me? you just did ! I said and quote "NGK PFR6b-11c, are the correct ones for European zeds " I then said "Need the 11c for the UK etc.

" the etc. refers to the original poster as I had said European and he is in the Netherlands, which is close enough eh?

 

The fuel in Japan has different ratings freely available 100 ron etc, the plugs fitted to non turbo in Japan with Jap spec ecu map end 11 with no C. If the cars are to be used outside of Japan and not the US then the C ones are correct........... wow need lie down now !

So I must have 11c if I understand well?

Simply YES 11c.

Thanks for the help guys!
