Spark plug heat range ..

[rOaD bEaSt]

I don't know if I'm using the correct spark plug or not .

I'm using fr7dpx bosch ..

I was always burning to top of the plug at the same time I replaced these spark plug and I increased the fuel jet ..

I called summit and they gave me NGK double platinum and I burned two sparks of them It costed me alot ..

But I don't really remember the part no of it ..

The stock spark plug is NGK-bkr6e .

How to go one step colder ?

Should it be bkr5e or bkr7e ??

Thanks alot I know that I'm asking so much
But I'm really intrested in asking you ..
Thanks all

NGK part number is PFR6B-11. Reduce the gap .004 for every 50 hp you add. Good luck!
