I had bought some plugs a while ago for my prelude engine which I never used. They are NGK Iridium IX part number ZFR6FIX-11
Does anyone know if I can use these on the S?

I have a AP1 2000 UK model

Thanks in advance

 

I just bought the same NGK Iridium IX plugs zfr6fix-11 (3668)

I was told they will fit the S2000 (AP1 2001)

Is someone using these on their S2K ?
Would also like to know before swapping to these.....


Thanks
Thomas

 

They'll fit, but they are one heat range hotter than stock. I wouldn't use them in a S2000.
