Hi guys,
I am driving a Wira SE, 4G15 siemens vdo fuel injection, 4-2-1 extractor... bla bla bla..
anyway, I saw from the Genuine Proton Parts kit that the spark plugs used for my block should be a heat index '5' plug but I already bought a set of heat index '6' plug. According to NGK's website I should be using a heat index '6' so which is correct?
What happens if it's supposed to be 5 and I use 6 instead?? won't cause detonation so easily right?
Thanks.
