Spark plug info. help needed
Hi everyone, I was looking to get some new plugs for my 97 JDM Accord EX F20B2 engine...
THE NGK plug specified for my car is the ZFR6F-11 however, this is an incredibly hard plug to find in the US, i'm much more likely to find the ZRF5F-11
The importance of this I am not sure of though, as the car is in Trinidad where the weather is basically in the 90's degrees F (~33 degrees C) all year long.. aka hot.. which is why I wonder the advantages of the 6 over the 5. I know that 6 designates a "colder" plug than 5, but I am unsure of quite how much difference it makes. Will it have any potential effect on performance?
The next thing is, I can get the 5 as the ZFR5FIX-11 aka Iridium. I understand that iridiums run a bit cooler than platinum or copper, so will this difference be enough to compensate for the 6 vs 5?
What would be the risks attached to running a plug that is too hot? Predetonation?
