Rb26 Plug Question

[MostH8D]

I took a look on several forums and got different answers to the same question. I need some clarification. I was told NGK pfr6a-11 plugs were stock but I see other ngk part numbers offered. Pfr6b-11 for example. Are these the same? What gap?.8 or 1.1 for a stock rb26? There is so little info in the U.S. Can you help?

Hey,

Anything with -11 after it will have 1.1mm gap. I put 1.1mm gap sparkplugs in my RB26 and it miss fired like crazy and had to re-gap anyways. Although my RB26 is modified so Im not sure if the 1.1mm gap ones will be fine for stock...
